George Clooney: I Didn't Leak F**kabees Footage

George Clooney claims he didn't leak footage of the infamous obscenity-laced battle royale between Lily Tomlin and director David O. Russell on the set "I Heart Huckabees" ... and he's betting a million bucks that you can't prove it!

In a statement to various media outlets, Clooney, who's famous for pranking just about anyone he can, said, "Contrary to popular opinion, neither the sound man, Ed Tise, nor yours truly sent in the David O. Russell tape. I saw it when we were working on "Ocean's 12," and there have been quite a few copies traveling around town for the last couple of years. Any rumor that either of us put it on the Internet is simply false.
And I'd offer a million bucks to anyone who would prove otherwise.
Your fan,
George Clooney"

That seems a pretty clear denial.
