I love Seinfeld! Love watching reruns, it's so much better than a lot of the rubbish that's on now.
Most of my faves have already been mentioned, there are so many good ones though..
The soup Nazi
The contest (master of their domain haha)
The one when Kramer burns down Susan's Fathers' cabin
The one where Susan dies (so morbid but it's hilarious at the end where they just go get a cup of coffee)
The one with the ugly baby
The Briss (spelling?) when Kramer tries to save the baby
The one where Kramer and Jerry switch apartments and the bright light makes Jerry turn into Kramer
George's Toupee (I don't like this thing, and here's what I'm doing with it!!!!)
The one with Elaine's nip*le when she shoves George's face into her chest
The one where they get lost in the car park, at the end when you can see them laughing and not holding it together in the car; it must have been such a fun job!
Ahhh so many classic episodes... I miss the 90s
