Is Charlie Sheen turning over a new leaf

Is Charlie Sheen turning over a new leaf.....
"I'm done with 'winning.' I have already won," he told the audience at the recent taping of "The Comedy Central Roast" for him. It airs at 10 p.m. Monday.
"This roast might be over, but I'm still Charlie Sheen. In here is an eternal fire. I just need to keep it away from a crack pipe."
Sheen seemed in good spirits throughout the taping, smiling, glad-handing with the press and laughing at his own expense. He's working on a new sitcom project for cable and focusing on a direction other than being tabloid fodder. For Sheen, the roast might be the swan song to that part of his life.
"I came out unscathed," he said of the barbs slung his way. "You're looking at a guy who thrives on chaos."
Sometimes the jokes hit very close to home ("His nostrils are so snotty and full of coke that he now refers to them as 'The Hilton Sisters' ") to jabs at his catchphrases ("Charlie, if you're 'winning,' there must be something wrong with the scoreboard.") Everyone onstage agreed on two things. Sheen's a mess, and they love him anyway.
The roast, which was taped last Saturday, featured a who's-who dais of wild fellas, such as Mike Tyson, Steve-O from "Jackass" and Duane Lee Chapman (better known as Dog the Bounty Hunter). None of them made excuses for Sheen's behavior over the past year. However, they all stood by him.
"When people are a mess, some are more dire than others," said Steve-O before the roast. "He told me he and I are a lot alike. We are all-or-nothing individuals, and when we go down, we go down hard. When we do it, we do it in legendary fashion. I couldn't help but be flattered.
"I don't know if he's misunderstood. I think he's doing most of the misunderstanding."
