George Clooney's Baffling History Of Elaborate Pranks

Convincing His Roommate That His Cat Took A Giant Human Poop

Clooney's most famous prank involves fellow actor Richard Kind of The Goldbergs and Curb Your Enthusiasm fame. Clooney crashed in Kind's apartment as an unemployed, recently divorced unknown actor in the early '90s and decided to repay his friend's hospitality via mental manipulation.  

It started with Kind commenting that his cat hadn't pooped in three days, unaware that Clooney had been emptying the litter box during that time. Instead of saying anything, Clooney continued secretly disposing of the poop and letting his friend worry about the cat's health. When Kind took the cat to the vet and started giving him laxative, Clooney says he simply upped his cleaning efforts. That is until he realized there was only one way he could end this prank: by squatting over the box, taking a crap, and then letting Kind find what he once described as "a chicken pot pie-sized human dump," which he briefly blamed on the tiny little kitten before the gross truth dawned on him.

Nearly 30 years later, Clooney still takes delight in telling the story, while Kind refuses to discuss it, except to say that 1) the laxative part is an embellishment, and 2) even if you manage to prank Clooney, the retaliation is just "not worth it," because he's" Machiavellian" and "Rasputin-esque" (presumably meaning that not even death could stop him from getting your ass back).

Shrinking Matt Damon's Wardrobe To Make Him Think He's Gaining Weight

Matt Damon is a common target for Clooney's pranks because there's just something about the guy that makes you want to watch him suffer. While shooting The Monuments Men, Clooney learned that Damon was trying to lose weight and had the wardrobe department tighten his clothes by an eight of an inch over a period of about a month and a half, to Damon's silent frustration. At least Clooney stopped short of having the props department slowly shrink all the furniture and such to convince Damon his diet really wasn't working.

Faking Other Actors' Stationery To Send Embarrassing Letters

One of Clooney's favorite weapons of prank warfare is mail fraud. As in, he will fake a letterhead from the name of a "friend" and send embarrassing letters to other famous actors, like when he posed as Brad Pitt and tried to make him look like an ass in the eyes of Tom Cruise and Don Cheadle. In one instance, he had "Pitt" send Meryl Streep a huge folder containing 60 CDs from a voice coach to "help her" prepare for her role in The Iron Lady, to Streep's years-long bafflement.
