[in a 1984 interview with the Washington Post] When [Chico Marx] did "Beer Barrel Polka" he would roll an orange on the keyboard. One time he threw the orange at me, and I threw it to the drummer, George Wettling. The next day everybody in the band had an orange and oranges were flying all over the stage. Chico loved it. "Leave it in," he said. "It's great."
