Practical jokin’ George Clooney NEVER quits!! He and Matt Damon hit the casino tables one night after shooting on “Ocean’s Eleven” — and George lost all his cash!

One problem: in the lower left corner, George had written: “FOR LAP DANCES!” You guessed it . . . shy Matt was too embarrassed to cash the check!
