According to Wikipedia, Joe Raposo, musical director of Sesame Street throughout the 1970's, was a student of Nadia Boulanger (along with Aaron Copland, Walter Piston, Roy Harris, Philip Glass, Elliot Carter, Burt Bacharach, George Antheil, Leonard Bernstein, Thea Musgrave, Quincy Jones, Michel Legrand, Roger Sessions, Virgil Thomson and Donald Byrd), a friend of Tom Lehrer, a very big fan of Spike Jones (responsible for Donald Duck's song Der Fuehrer's Face), and he set the music for Eric Bentley's English translation of Brecht's A Man's a Man.
This was, apparently, his favourite joke:
"'Recently, a man got on the shuttle flight from New York to Boston and took a seat next to a prim, middle-aged woman who was wearing a gray suit. From his briefcase, the man took out a copy of Playboy, unzipped his fly, and opened the magazine to the centerfold. Holding Playboy in his left hand, he masturbated to completion with his right hand. When he finished, he dropped the magazine, removed a handkerchief from his jacket's inside pocket, and cleaned up. When he was done, he folded the handkerchief and put it back in his pocket, before returning the magazine to his briefcase under his seat. He then turned to the woman next to him and said, 'Pardon me, do you mind if I smoke?'"
