Everything was going along rather normally on 'Jimmy Kimmel Live' Monday night. He was interviewing Mark Cuban, but in doing so they inevitably started talking about Charlie Sheen. What they may not have realized is that all that tiger's blood in his veins allows Sheen to hear his name being mentioned anywhere in the greater Los Angeles area.

"Charlie's a smart guy," Cuban was saying. "He doesn't get near the credit that he deserves for being smart." At that moment, Sheen erupted onto the set, flinging curse words and T-shirts at Jimmy Kimmel's audience. He'd brought in several samples of his own line of T-shirts emblazoned with his new catchphrases, like "Duh, Winning!" and "I Have Tiger's Blood in Me."
