Back when he was working at the MGM Grand, [Carrot Top] would watch George Carlin from behind the curtain at the side of the stage. Like a lot of artists, Carlin had the rituals that give performers facing unpredictable rooms the illusion of control. There was a vending machine backstage, and one of Carlin’s tics was checking the change-return slot each time he went onstage and checking it each time he walked off. There was never any money in it. So one night, Thompson decided to slip out of his hiding spot and plant a quarter in the change-return slot. He watched Carlin finish his set, check the slot, and beam when he found the quarter. “It’s funny,” Thompson says. “It was the smallest thing.”
