The Muppet Show - 223: John Cleese - Backstage #3 (1978)

Floyd and Fozzie make more arm jokes. (Floyd: “What is red and woolly and five feet long?“ Fozzie: “I don’t know, Floyd. What is red and woolly and five feet long?“ Floyd: “A mitten for Gonzo the Great!“) Gonzo comes to John’s dressing room for help. He tells John that he wants his arms to be the same length again. John helps by stretching the other arm out, so that they’re both long. When Gonzo complains of this, John brings Gonzo’s arms back to their normal length by stretching Gonzo’s legs out. But now Gonzo can’t tie his shoes, so John stretches out Gonzo’s arms. Gonzo ends up pulled completely apart.
