Statler and Waldorf put on a production of the burlesque song "Take Ten Terrific Girls" for the opening number in episode 409 of The Muppet Show. The songs lyrics state "Take ten terrific girls, but only nine costumes..."; sure enough one of the Muppet Whatnot girls in the chorus line finds herself onstage without any costume. The tune can also be heard at the end of "Make 'Em Laugh" in episode 403.
