The Muppet Show - 213: Rudolf Nureyev - Backstage #2 (1978)

Appalled by the number, Sam is relieved to learn that Rudolf Nureyev was not around to hear it. An unidentified man arrives, announcing, “I’m here!“ Sam responds, “Not for long you’re not!“ Assuming the man to be some “freak,“ Sam kicks him out of the theater. Sam: “Who do these punk kids think they are?“ Kermit: “Well, that one thinks he’s Rudolf Nureyev. In fact, that was Rudolf Nureyev.“
