My favorite episode from Seinfeld is the Chicken roaster. Here is a quote fromt he chicken roaster:
Kramer: Kenny..Kenny..Kenny..Kenny..Kenny.
I also like the soup Nazi episode.
SEINFELD! KENNY!

Cosmo Kramer: "That was a close one."

Newman: "Why do we have to keep this a secret from Jerry?"

Cosmo Kramer: If Jerry finds out I'm hooked on Rogers' chicken, I'm back there with the red menace."
