Brad Pitt has warned Ashton Kutcher against playing a practical joke on George Clooney. The Hollywood heartthrob interviewed Ashton, who is renowned for winding celebrities up on his MTV show 'Punk'd', for America's Interview magazine and he advised him not to target Brad's 'Ocean's Twelve' co-star. He said: "I remember two years ago you were after Clooney. I would tell you as your friend: 'Don't do it. Don't ever go near it. He'll kill you and everything you love.' I know it's tempting, but don't do it." Brad himself has been on the receiving end of George's practical jokes before. During the filming of 'Ocean's Twelve', the 41-year-old star was left red-faced when George stuck a bumper sticker on his car claiming he had a small manhood. Their co-star, Matt Damon, revealed at the time: "Brad was sitting in his car and George tapped the car with his hand and said, 'All right, take care.' "When he pulled his hand away, he left a bumper sticker that read 'Small Penis Onboard.' Brad drove through rush-hour traffic in Los Angeles with it, and all these people were looking at him and waving."
George is famous for his practical jokes and once even put his own faeces in a flatmate's cat litter tray.
The actor, who used to share an apartment with 'Spin City' star Richard Kind, put his own excrement in the tray - after convincing Richard the pet was constipated.
