This is my favorite scene from the entire Seinfeld series. It came during the penultimate show, "The Puerto Rican Day." It is the first time that Kramer, Jerry and George's alter egos (Pennypacker, Varnsen and Vandelay) come together in the same room. To me, this scene really was the culmination of the show about nothing. 

I have been trying to find this clip for a while but always seemed to hit a dead-end. Recently one of my friends made an "Art Vandelay" comment which prompted me to take another shot at finding the clip. I guess if you wait long enough, everything eventually ends up on the internet.

Apparently their was a huge controversy surrounding the show due to the accidental burning and stomping of the Puerto Rican flag by Kramer. NBC only aired the episode once and removed it from syndication. It was the second highest rated episode behind the series finale.
