In "The Simpsons" episode "All About Lisa", Sideshow Mel takes Lisa Simpson aside after she becomes Krusty the Clown's assistant. He tells her that the key to dealing with Krusty is to always be prepared to cater to his needs—have a cigar at the ready, never directly look him in the eye, and pretend to know who Mitzi Gaynor is if he mentions her – he always does. She then uses this reference when Krusty says Lisa is the best thing since... "Mitzi Gaynor!" Lisa exclaims.
