Charlie Sheen charged the Jimmy Kimmel Live stage Monday night and planted a smooch on the "moist lips" of the surprised late night host.

The audience greeted Sheen with thunderous applause as he barreled in, and he rewarded their enthusiasm with high-fives, autographs and, later, novelty T-shirts sporting some of his most famous quips.

Sheen, 45, also showed guest Mark Cuban – with whom he's considering going into business – some serious affection, giving the billionaire a bear hug.

But amid the applause, Sheen got down to business. "Silence," he commanded the audience, "I have a show to write," referring to his upcoming Charlie Sheen LIVE: My Violent Torpedo of Truth concert tour.

And, just like that, the actor was gone.
