I ett av de roligaste Seinfeld-avsnitten får Kramer felaktigt någon annans personliga registreringsskyltar till bilen.

[At the motor vehicle bureau]
Kramer: Yeah, I’m here to pick up my new plates. My name is Kramer. Cosmo Kramer.
Clerk: Kramer. [checks computer] All right.
Kramer: All righty.
Clerk: Sign right here, please. [hands over clipboard]
Kramer: [signs it] Okay. [the clerk hands him a manila envelope]. Thanks. [opens up the envelope] Assman? Oh, no, these don’t belong to me. I’m not the Assman. I think there’s been a mistake.
Clerk: What’s your name again?
Kramer: Cosmo Kramer.
Clerk: [checks computer again] Cosmo Kramer. You are the Assman.
Kramer: No! I’m not the Assman.
Clerk: Well, as far as the state of New York is concerned, you are.
[Failing to clear up the mistake, Kramer drives off with the new plates attached]

Skyltarna visade sig sedermera tillhöra en proktolog.
