CULVER CITY, Calif. (AP) — Charlie Sheen smiled through a Comedy Central roast as Mike Tyson, William Shatner, actress Kate Walsh and half a dozen comedians riffed on his high-profile year.

Sheen was famously fired from his sitcom “Two and a Half Men” in March after a very public meltdown during which he claimed to be a “rock star from Mars” who has “tiger blood” and “Adonis DNA.”

The 46-year-old actor is the subject of the latest roast, which was taped Saturday night at Sony Studios and will air Sept. 19 on Comedy Central.

Sheen took the stage in true rock-star fashion, as rock ‘n’ roll guitarist Slash heralded his introduction. The actor, dressed in a black suit, white shirt and red tie, smiled and laughed as roasters jabbed at his famous family, his notorious taste for drugs and prostitutes and his primetime firing.

“Charlie’s meltdown was so bad, Al Gore’s making a documentary about it,” quipped comedian Jeffrey Ross, who was dressed as Muammar Gaddafi in a military outfit with fringed epaulets and a sash.

Comedian Jon Lovitz also took a timely swipe at Sheen: “How much (cocaine) can Charlie Sheen do?” he asked. “Enough to kill two and a half men.”
