Hollywood producer Jerry Weintraub was caught out by pranksters Brad Pitt and George Clooney on a boozy flight to Los Angeles - the pair filled his underpants with M&M's after he fell asleep.
The trio was flying to back to California after a trip to Italy, where they were promoting their Ocean's Thirteen film, when the actors challenged him to a drinking contest.
But the practical jokers didn't tell Weintraub that they were secretly filling their glasses with water.
The movie mogul remembers, "We drink one bottle, two bottles - we get on the third bottle and I started feeling woozy, and I never get like that. I could drink forever. These guys are drinking with me and I'm woozy and they're fine.
"And all of a sudden I pass out. I get on the couch and I sleep all the way to L.A."
And the Hollywood heavyweight was in a rage when he woke up, hungover and with a wod of melted chocolate down his pants.
He says, "When I got up I felt squishy stuff in my shoes, in my underwear, in my clothes, and they put M&M's in my underwear... I said, 'You sons of b**ches! What did you guys do to me?'
"I found out from the pilots and the stewardess they were drinking water."
