"Hollywood is filled with pranksters... and none of them more mischievous than George Clooney. Rumor has it that when he's at a party (and trust us, he's at plenty), Clooney will go around stealing cameras while people aren't looking, take a picture of his own derriere, then return the camera. Then, a few days later, when people are showing their friends pictures..."
[When George Clooney and Brad Pitt found out that Julia Roberts would be joining be cast of Ocean's Eleven, the pranksters sent her a $20 bill inside a card reading: "We heard that you get 20 per film." Clooney also set a collegial tone on the set -- by showing up with eleven fire-engine red bicycles, stenciled with the cast members' names.]
