Everett "The hardest part for me was when they put Agent 13 in a washing machine,"Ketchum recalled in a 2002 interview. I'm 6′2″, so I can't fit easily into cramped places, and a washing machine is about as cramped as it gets. They also built an 8-ft. tube I got into so I could be spun around in the front. You try remembering your lines while you're spinning around with water and soap squirting in your face!" The series, created by Mel Brooks and Buck Henry, concluded a five-season run in 1970.
