The only show in the history of man where you have to watch it to get the funniness of the jokes.
Kramer: Hey you want a Junior Mint?
Jerry: No I'm good.
Kramer: C'mon they're chocolatey and refreshing. They're delicious!
Kramer: (hands one to Jerry and it falls into guy getting operated on).
That joke might not have seemed funny here, but if you watch it you'll laugh your fucking ass off. It's the perfect example of a Seinfeld joke.
