The Apartment
The Parking Space
The Non-Fat Yogurt (I like the ad-lib stand up)
The Opposite (I like the Phrase "Hire this man")
The Abstinent (Elaine doing the crossword and tire things were funny)
The Conversion
The Marine Biologist
The Chicken Roaster (Jerry turning into Kramer)
The Frogger
The Serenity Now (I have actually said that at School)
The Little Kicks
The Andrea Doria (Kramer turning into a dog)
The Marine Biologist Episode is great with how everything ties together at the end.
Another one of my favorites is The Car Dealership one, with the "Twix lineup" and Kramer "breaking off the needle".
Ive always disagreed when people say Seinfeld is a show about nothing....because it's a show about everything. There isn't much that hasn't been in a episode of seinfeld and that's whats great about that show.
I like the one where there on the Airplane and Elaine gets stuck in Coach and Jerry gets first class. That happened to me once with a family member. I was the lucky one. MMM do I smell chocolate and hear the sound of champagne being poured?
