Norma Jean Monster
This goth rock duo was a Marilyn Manson/Alien Sex Fiend parody (complete with face paint) that went to a New Age relationship camp in a sketch from the "Flat Top Tony and the Purple Canoes" episode (10/10/1997) of the HBO sketch comedy show Mr. Show with Bob and David.
They had a blast. Dave Cross was Norma Jean Monster, Bob Odenkirk was Adolph Hepburn. Their interviewer Chrysalis was played by Sarah Silverman.
