After taking an unprecedented amount of abuse at his Comedy Central roast that aired Monday, Charlie Sheen picked himself up, took the mic with swagger and delivered a heartfelt speech letting the audience know he’s still in the game.

"Wow, what a night -- until tonight, I never realized how f***ed up I was," Sheen said. "All this time I thought I was just having fun. The thing is once again, I come out unscathed.

"You can't hurt me -- hell, I can't even hurt me! Drugs couldn't kill me. Sex couldn't kill me. The press couldn't kill me. Two and a Half Men couldn't kill me. Did you really think your little jokes were going to kill me? I'm done with the winning cause I've already won.

Despite standing before a verbal firing squad for 90 minutes, Charlie Sheen left Monday night's Comedy Central roast without a scratch -- Steve-O, well that's a different story.

The Jackass star took the phrase "physical comedy" to a whole new level, ending the show by literally diving into the champion boxer's fist, a promise he made to his pal Sheen earlier in the night. He emerged bloody and bewildered with a broken nose, drawing a confused stare from William Shatner (who's presumably seen every life form in the galaxy).

Sheen later posted a photo on whosay of Steve-O, sporting a black eye and wrote:
“This is what @SteveO looked like the morning after the #SheenRoast - it's like a medical mugshot. You crazy bastard.”

Charlie Sheen and his father Martin Sheen team up in a hysterical new ad for the upcoming Comedy Central roast of the former Two and a Half Men star.

In the ad Charlie, with his face painted camouflage, emerges from a body of water like his dad Martin in the 1979 classic, Apocalypse Now saying, “I was going to worst place in the world -- cable.”

At that point, the real Martin Sheen shows up, yelling at Charlie, who's actually in a swimming pool, flanked by two bikini-clad beauties.

No sleazy stone was left unturned as Charlie Sheen was the center of attention at a Comedy Central roast in his honor this past weekend.

A cast of comedians and stars -- including Grey’s Anatomy star Kate Walsh, Guns N' Rose guitarist Slash, boxer Mike Tyson, Star Trek’s William Shatner and Jackass star Steve-O -- gathered for the Saturday event at Sony Studios in Culver City, California.

They took no-holds-barred slams at the actor's hard-partying reputation, including his admitted drug habit, his firing from Two and a Half Men (the highest-paid gig in TV history); and his former living arrangements with the Goddesses (porn star Bree Olson and model Natalie Kenly).
