The Muppet Show - 307: Alice Cooper - Backstage #1 (1978)

As the band enters backstage, Kermit remarks the Julie Andrews show was more pleasant and calls for the William Tell act to get onstage. He then tells Alice how great being a rock star might be. Alice then offers him a sinister contract, which can ensure his wildest dreams for one price: his soul. One of the stray arrows impales the contract onto the banister. The act comes backstage, with William Tell's assistant having an arrow through his head.
