Quote from Jerry in The Fire
Jerry: Hey, what's the deal? What was going on there? I invite you down here, I have an important show, and she heckles me?! Kramer: Look, she didn't mean anything. Jerry: Well, what is the matter with her? Is she crazy?! Kramer: She's just being enthusiastic, that's all! [Toby enters] Jerry: Hey! What is wrong with you?! Toby: Me? Nothing's wrong with me. Jerry: You boo me?! You hiss?! You didn't stop blathering throughout the whole set! Toby: Oh, come on. I thought you're a pro. That's part of the show. Jerry: No, not part of the show! Booing and hissing are not part of the show. You boo puppets! You hiss villains in silent movies! Toby: Well, that's the way I express myself. How are you gonna make it in this business if you can't take it? Jerry: Oh, I can take it.
