Kramer: Hey, smell my arm. Smell it!
George: No, with all due respect, I don't think so...
Jerry: That smells good, what is that?
Kramer: The beach.
Jerry: The beach?
George: What, did you go swimming? It's 29 degrees out!
Kramer: No, I just joined the Polar Bear Club.
Jerry: You joined the Polar Bears?
George: What the hell is a polar bear?
Kramer: Well, it's these people. They go swimming in the winter. They're terrific. I just took my first swim today. Brrrrrrr! It's invigorating!
Jerry: Yeah. So's shock therapy.
