I liked the one where Jerry is doing stand up and he gets booed by Kramer's girlfriend. She works with Elaine and he gets revenge by going to her office to heckle her. She runs out of the building and loses her toe because of a street sweeper.
I kill myself laughing in the next scene when Kramer describes how he finds her toe then has to take the bus to the hospital to give it to her.
"You're Batman!"
