Charlie Sheen is reportedly in business talks with Dallas Mavericks owner Mark Cuban, so his cameo during Jimmy Kimmel’s interview with Cuban yesterday didn’t exactly come as a surprise. The lingering man-kiss, however, probably was. Radar Online says:

Upon making his grand entrance, the former Two and a Half Men star, 45, planted a huge kiss on Kimmel, and took the first seat.

“I can’t stay… I can’t stay sorry — silence! I have a show to write damn it!” he said, referring to his stage show.

Sheen then pulled out a few bags of his t-shirts — emblazoned with phrases like “Tiger’s Blood” and “Winning” — and tossed them out to the studio audience.

Sheen then gave Kimmel a coffee mug with a picture of a fox on it, telling the late night host, “I’ll let you figure it out.”

In case you didn’t pick up on the elusive fox-on-a-mug riddle, Charlie Sheen is also reportedly in talks with the Fox Network. The Daily Mail says:

The Hollywood Reporter said Sheen met with senior executives at rival network Fox last week for talks.

The actor sent a cryptic Tweet over the weekend reading ‘perhaps a new lair…? A Fox and a Warlock? epic’ accompanied by a picture of a Fox television logo.

Okay, back to that kiss. Jimmy Kimmel wasn’t wearing a dental dam when it happened, so he probably has full-blown mouth herpes now. Possibly even Hepatitis A and early-onset gingivitis. You can’t be Ground Zero for Charlie Sheen contamination and not suffer any long-term oral side effects.
