Here are some scenes I can recall that have been cut from the sydicated episodes of Seinfeld that will forever air in the TV show heaven of Reruns...
Jerry's Monologue on Handkercheifs ("snotrags") from "The Opposite"
JERRY:"Believe me Kramer, given the proper legal president, I WILL kill you!" -from "The Comeback"
there are so many more...add your memories..
