Actor Charlie Sheen has delivered some unforgettable rants over the years. Who can forget the time he called "Two and a Half Men" creator Chuck Lorre a "sociopath," or when he took on all of the "Men's" execs at once? But his latest rant has nothing to do with his old sitcom angers. This time, it's personal.

"CADRE! This is a legitimate call to arms," he told his Twitter followers Wednesday night. "My daughter Sam was bullied out of Viewpoint school and then called a liar. it's on!"

And when the self-dubbed warlock says, "it's on," he means it.

Without sharing further details of the alleged bullying, the 47-year-old father actually went on to urge his followers to help him seek revenge by delivering rotten eggs, toilet paper and dog waste to his 9-year-old daughter's former school -- "with extreme prejudice."

Read the full rant, which includes a "show and tell" suggestion, here -- but be warned, the warlock uses harsh language for his harsh message.

TODAY.com reached out for comment from the actor's publicist, but has not received a response.

Lindsay Lohan is set to guest star on Charlie Sheen's "Anger Management.

Charlie Sheen has a new goddess, and her name is Lindsay Lohan. FX announced on Monday that the actress is set to guest star as herself on an upcoming episode of the actor's "Anger Management."

According to the network, the troubled starlet will develop a romantic relationship with Sheen's character, Charlie Goodson. This will come about after she becomes one of his therapy patients. No specific air date has been announced, but FX noted that the episode would air sometime in April.

This won't be the first time the two have worked together. Sheen and Lohan both had small roles in the film "Scary Movie 5." Like Lohan's episode of "Anger Management," the movie is scheduled for an April release.

While filming "Scary Movie 5," rumors surfaced that the actress refused to smooch the actor. Regardless of whatever went down on the set of the film, the two have been pretty chummy as of late, with Sheen giving her $100,000 to pay off some back taxes, offering to give her advice, and now a guest role on his hit show.

"Anger Management" airs at 9:30 p.m. Thursdays on FX.

Charlie Sheen isn't a fan of Lance Armstrong.

"He's kind of a douche," the "Anger Management" star told Jay Leno on Wednesday's "The Tonight Show." "Wow, I didn't just say that, did I? ... That's based on meeting him."

Sheen recalled his first encounter years ago with the now-disgraced cyclist, who, after years of denials, recently admitted in an interview with Oprah Winfrey that he used banned substances and blood doping to win seven Tour de France titles. Sheen said he introduced himself to Armstrong, who pretty much dismissed the actor.

"He said, 'That's nice,'" Sheen said. In an aside to Leno, Sheen pretended to address Armstrong: "Sorry to bother you, Captain Bitchin'. Go get a paper route, dude."

Leno added that Armstrong is getting more heat than he might have not just because he "cheated, but the fact that he ruined the lives of people" who called him out. Sheen -- who himself is no stranger to scandal -- agreed.

"If he was a better guy ... in his life, he'd be forgiven a lot faster and a lot easier -- kinda like me," he said to audience applause.

Sheen also weighed in on the rumor that he recently gave $100,000 to troubled star Lindsay Lohan. After joking that was "just for dinner," he revealed that it had to do with their appearances in the upcoming "Scary Movie 5." He said that when Lohan signed on for the movie, she was supposed to be given half of Sheen's salary but was shorted.

"They took half of my money to give to her, and she didn't get it all," he said. "So when I found this out, I said, 'You got shorted a hundred grand.' So I gave it to her."

He added of Lohan: "She's going through some stuff, but she's smart and super talented, and I think she will come out on top."

Cassandra’s mother is the actor’s high school girlfriend Paula Profit.

Charlie and Denise, who were married from 2002 to 2006, have two children together, Sam, 8, and Lola, 7. The actor also has 3-year-old twin sons, Bob and Max, with Brooke Mueller -- who Denise often looks after when needed. 

“They’re our family and they’re Sam and Lola’s brothers and I can’t imagine growing up without my sister, so anytime she needs help, I’m there for the boys,” she said during a visit to "Access Hollywood Live" in December. “[Sam and Lola] are the best big sisters to [the boys] and they love them.”

Charlie Sheen just upped his good-guy credentials. The "Anger Management" star, no stranger to being hounded by the paparazzi, generously sent a $12,000 check to help cover funeral costs to the family of the photographer who was killed last week while trying to snap a picture of Justin Bieber's car.

"A tragic incident like this erases the line between the photographer and the subject. It's an unforgiving moment that begs us all to be human and work as one to prevent this in the future," Sheen told E! News through his rep. "As parents, we are all not supposed to bury our children. My deepest condolences to the families involved."

Justin Bieber paparazzo death: Chris Guerra remembered as a "sweet" guy

Chris Guerra, a 29-year-old paparazzo who was described as a "sweet" guy by his peers, crossed Sepulveda Boulevard by Los Angeles' Getty Center and the 405 Freeway to try and get a shot of the teen idol's white Ferrari, which had been pulled over by police, when he was tragically struck by a car driven by a 69-year-old woman and subsequently died. (It turned out that the driver of Bieber's vehicle was actually the singer's rap buddy Lil Twist.)

Sheen decided to pitch in after a plea from a photog pal who was friends with Guerra and was trying to raise money to help the latter's family with the funeral expenses. The wake was being held Thursday.

All we can say is way to go, Charlie.

Here are some other celebrity do-gooders

Charlie Sheen has Adonis DNA, tiger blood and apparently a heart of gold.

The "Anger Management" star donated $75,000 on Sunday to help a 10-year-old girl named Jasmine Faulk beat cancer. Charlie's stunt double, Eddie Braun, also cut a $25,000 check to the Hermosa Beach Police Officers Association (Jasmine's dad, Everitt, is an officer), which is fundraising for Jasmine's treatment of a rare form of pediatric cancer called alveolar rhabdomyosarcoma.

Charlie also gave Lindsay Lohan $100,000 to help her out of debt

"Big news today for the Faulk family. Together, Eddie Braun and Charlie Sheen donated $100,000.00 to the HBPOA in support of Jasmine's fight against cancer," the organization posted on their Facebook page Sunday. "All proceeds go to the Faulk family to support their daughter. On behalf of the HBPOA, the Faulk family and those who support children fighting cancer, we thank you for your generous donation."

A tumor was found in Jasmine's facial sinuses in September 2012, and according to Facebook, she will "go through very aggressive medical treatment, including chemotherapy and radiation for one year."

We truly wish her the best, and applaud Charlie and Eddie for their winning generosity.

Lindsay Lohan.

 Hollywood bad boy Charlie Sheen found a kindred spirit in actress Lindsay Lohan when they worked on the set of "Scary Movie 5" and gave the actress $100,000 to pay off some of her overdue taxes.

Sheen's camp on Monday confirmed that the "Anger Management" star gave the cash gift to the in-and-out-of-trouble Lohan who reportedly owes the U.S. government more than $200,000 in unpaid taxes for 2009 and 2010.

"Charlie has a long history of helping out his friends in many ways and this is just another example of that," Sheen's publicist Larry Solters said in a statement.

Sheen and Lohan worked earlier this year on the horror spoof "Scary Movie 5" which is scheduled for an April 2013 release.

Lohan's latest performance as late Hollywood screen legend Elizabeth Taylor did not go so well. Her role in the TV movie "Liz & Dick" was slammed by critics and largely ridiculed on Twitter. Cable TV channel Lifetime said on Monday that a modest 3.5 million Americans watched the film at the weekend. 

Lohan and Sheen's hard partying and off-screen antics have made them tabloid favorites. 

Lohan, 26, has been mired in legal and financial troubles and since 2007. Sheen, 47, once the highest-earning actor on television, was infamously fired from CBS comedy "Two and a Half Men" in 2011 after making derogatory comments about the show's creator, Chuck Lorre. 

During that time Sheen gripped the public in a meltdown of drug use, erratic behavior and Internet soliloquies.

Sheen has cleaned up his image in recent months while starring in "Anger Management" on cable television channel FX.

LOS ANGELES -- Forget winning; Charlie Sheen is all about giving at the moment. The "Anger Management" star announced Monday that he will donate $1 million to the United Service Organizations (USO), which will go toward the USO’s Operation Enduring Care, an ongoing campaign to support wounded, ill and injured troops and their families.

"It's an honor for me to be able to give back to these men and women of the military who have done so much for all of us," Sheen said of the donation. "They put their lives on the line for us every day, and I'm just happy that my work on 'Anger Management' can bring a little bit of relief to the troops and their families."

The actor has pledged to donate 1 percent of the profits from his FX comedy "Anger Management" to the USO, with a guaranteed $1 million minimum.

"The USO would like to thank Charlie Sheen for his very generous $1 million donation to our Operation Enduring Care Campaign and his interest in helping us lift the spirits of those who have endured so much to protect the freedoms we enjoy daily," Gen. John I. Pray Jr., executive vice president for the USO, said of the donation. "His support is greatly appreciated, especially from our wounded warriors and their families."

The actor has been making efforts to harness his star power for philanthropic ends recently. Last week, Sheen entertained "American Idol" executive producer Nigel Lythgoe's suggestion that he should become a judge on the singing competition, noting that he'd be up for it on the conditions that a) FX gave him the green light and b) "Idol" makes a significant donation to charity.

"If the numbers move the needle and 'Idol' matches 20 percent of my weekly salary for Autism Speaks, [the diabetes charity] JDRF, and the Boys and Girls Club ... then the hell with it. As we say, pour the smoke," Sheen told TMZ.

Last October, Forbes named Sheen the highest-paid actor on TV, noting that he'd raked in $40 million between May 2010 and May 2011.

Charlie Sheen, shown in 2009, told his Twitter followers to "reach for the stars" before signing off.

Charlie Sheen, who made the Twitter hashtag "#winning" as popular as his account — he garnered 2 million followers after being on Twitter for less than a week — says he's signed off the microblogging site. Whether it's permanent remains to be seen.

A few days ago, the star of the new FX show, "Anger Management," posted this Twitter message Thursday, saying "reach for the stars everyone.
dogspeed cadre. c out" on Twitpic, then his Twitter account went dark:

msnbc.com

The former star of "Two and a Half Men," Sheen first got on Twitter to vent his rage after being taken off the show in March 2011. In addition to "#winning," another popular hashtag became "#tigerblood," something he told NBC's Jeff Rossen he had, in terms of being invulnerable to addiction.

Sheen was so intense on Twitter, he even hired a "social media intern" to help him manage his posts. At the time @charliesheen went dark, Sheen had 7.7 million Twitter followers, according to Twitter Counter. (No. 1 is Lady Gaga.) 

TMZ said Sheen said in an interview he wanted to thank his followers for their support. "hank you all for your amazing support. Trust me when I say please ‘follow’ me to my next endeavor. It’s gonna be epic" he told the entertainment website.

Less than three months after his induction into the Rock and Roll Hall of Fame, Slash received a star on the Hollywood Walk of Fame Tuesday. Speakers included producer Robert Evans, radio host Jim Ladd and Charlie Sheen, who had the best line of the ceremony.

Charlie Sheen speaks as Slash (Saul Hudson, right) is a honored with a star on Tuesday, July 10, in Hollywood.

"It's quite fitting that Slash is getting a star on the very street Axl Rose will one day be sleeping on," he said. "This star is going to be stepped on more than the coke we did in the '80s."

Slash covered his face to hide his laughter during the Axl crack, but if the odds of a Guns N' Roses were a trillion-to-one before Tuesday, they just got a bit slimmer. Also, don't expect Axl to be guesting on Sheen's new show, "Anger Management," anytime soon – regardless of how badly he needs actual anger management.

Our three picks for the best entertainment of the week include one TV show, one movie, and one new DVD. We can vouch for the quality of the DVD, and the movie looks promising, but with the TV show ... who knows? Charlie Sheen has proven he can be funny, but will he recapture the "Two and a Half Men" magic with his latest (and final, he says) sitcom? Time will tell.

TUESDAY: 'The Artist' on DVD
Who knew an almost-silent, black-and-white movie would be the big winner at the Oscars? If you didn't get to see this year's best picture winner in theaters, now's your chance to check it out on home video. The film tells a sweet and sad tale of two actors on opposite career trajectories (cue "A Star is Born") just as Hollywood is switching from silents to talkies. It's touching and happy, and cute little dog Uggie is the best cinematic canine since Benji or Lassie. (On DVD and Blu-ray June 26.)

THURSDAY: 'Anger Management'
For a while there, it seemed as if Charlie Sheen was making entertainment headlines every day. In 2011, the longtime actor was fired from "Two and a Half Men" over a much-publicized dispute with show creator Chuck Lorre, and after that, his girlfriend goddesses, "tiger blood," and "winning!" catchphrase were everywhere. Now Sheen's quieted down a bit -- he even apologized to former co-star Jon Cryer, whom he once called a "troll." He'll  try and capture audiences again with his new comedy, "Anger Management," loosely based on the 2003 Jack Nicholson-Adam Sandler movie. No one at FX will be angry, though, if the show captures even a part of the "Two and a Half Men" fanbase. (Premieres June 28, 9 p.m., FX.)

FRIDAY: 'Magic Mike'
Get your girls' night out group together now for "Magic Mike," the film version of a stripper-packed bachelorette party. Channing Tatum plays the experienced stripper who teaches the trade to Alex Pettyfer, but Matthew McConaughey steals the trailer as a charismatic former stripper who owns their dance club. Warning: The film's not in 3-D, so leave your dollar bills at home. (Opens June 29.)
