Quote from Jerry in The Stand-In
Jerry: Why does this guy Johnny have it in for you? Mickey: Oh, he's always been jealous of me. I always get to stand in for the bigger stars: The Cosby Kids, Ricky Schroder, Macaulay Culkin. Kramer: [whistles] What's he like, huh? Mickey: He's a good kid. Kramer: Yeah? Jerry: So what does he care if you put lifts in? Mickey: You don't understand. There's an unwritten code about this kind of thing. I could be ostracized. I remember when I was a kid, some guy tried to heighten. He lost his job, lost his friends, Everything. Oh, I knew I was crazy to try this kind of thing, but I was so desperate. What is this kid taking anyway? Hormones? Steroids? Would you tell me!?
