Faust

Faust is the protagonist of a German legend; a highly successful scholar but one dissatisfied with his life who therefore makes a pact with the Devil, exchanging his soul for unlimited knowledge and worldly pleasures. Faust and the adjective Faustian imply a situation in which an ambitious person surrenders moral integrity in order to achieve power and success for a delimited term.

In The Muppet Show episode 307, guest star Alice Cooper, moonlighting as a servant for Satan, offers the Muppets a contract promising "fabulous riches and worldwide fame" in a Faustian exchange for their souls. Kermit shudders at the idea, Miss Piggy gives it a test run but ultimately decides it's not worth the sacrifice (or the makeover), and Gonzo spends much of the episode looking for a pen to sign the contract. He becomes so desperate that he, in quick succession, offers to trade the Vile Bunch Drummer a chicken, all of his chickens, and finally his soul for a pen before realizing that he has "other plans for that."

In the Dinosaurs episode "Life in the Faust Lane", upon viewing a commercial for a mug advertised as the key to happiness, Earl Sinclair sells his soul to the Devil in order to obtain one.
