It's always fun to remember that he played himself in the 1986 Rodney Dangerfield movie "Back to School". I always have to double check this when I think of it, partially because I confuse it with the time Ernest Borgnine played J.D. Salinger in an episode of "The Single Guy". It's almost like Vonnegut decided to do this only because people would some day think it sounded so obviously ridiculous and false.
