Kramer

You know why Rifkin was a serial killer? Because he was adopted. (saying it as he's taking a lot of paper towels from Jerry's roll; Elaine and Jerry are confused at Kramer's statement) Just like Son of Sam was adopted. So apparently adoption leads to serial killing. (Kramer leaves and we don't know why he needed so much paper towels)

Elaine

You know Joel and I have an extra ticket to the Giants game.

Kramer

I'll go.

Elaine

O.K. I'll leave the ticket for you at will call.

Kramer

Yeah! Ooh! (leaves again)
