In the Lola Falanna episode, Gonzo prepares to leave the Muppet Show, and he is replaced by "Trevor the Gross," who immediately starts to hit on Camilla. Gonzo takes this in stride, until Trevor tries one of Gonzo's stunts. That's enough to make Gonzo want to stay. Of course it all goes horribly wrong, but Gonzo's artistic integrity will not be besmirched!
Gonzo: That's it! You can steal my job, you can steal my girl, but you will not steal my act!
