Damon, Pitt Behind Clooney's Stripping Man-Fan?

Thinking this is the beginning of a great prank war between these 3. I can only imagine what Clooney comes back with.. These guys could do their own mini-series on Punk’d! That would be awesome, I’d need to set my tivo for that, wouldn’t want to miss it! -Greg

The very-much-alive Matt Damon turned up on the Late Show With David Letterman last night and, aside from breathing, made some news by offering a possible explanation for buddy George Clooney being ambushed by a clothes-eschewing would-be gay lover at the Venice Film Festival earlier this week.

It was Damon’s fault. And Brad Pitt‘s.

As Damon tells it, Pitt was getting so fed up with Italian journos’ queries about when he was going to tie the knot with Angelina Jolie, he finally blurted out that he’d do the deed once “George Clooney marries his boyfriend.”

“So this Italian journalist comes in and goes, Matt, is it true what Brad say?” Damon, in his best Eye-talian accent, recounts to Letterman. “And I have no idea what he is talking about. But you know, I go, ‘Yeah, of course it’s true.’ And he says, ‘Do you mean George Clooney have a boyfriend?’ And now I’m trying to keep a straight face and I go, ‘Yeah, of course he’s got a boyfriend. And he wants to legally marry him. We’ve been on him about this for years…’ ”

Flash forward to Tuesday: Damon turns on CNN and “this guy stands up and says, ‘George!…I am a gay.’ And this guy starts peeling his clothes off and he says, ‘If you musta choose, choose me!’ ”

“I’m sure George is still laughing about that one,” says Letterman.

Right. All we can say is watch out, Damon. Payback’s a bitch.
