This is how I think the final Seinfeld will end. At the end of the show, during the stand up, Jerry will be doing his routine when all of a sudden there will be an insane screaming from the back of the room. Jerry will raise his hands, blocking the glaring lights and squint to make out the figure. A terrified look will overcome Jerry as he realizes who it is... Babu!!!! Babu will chase Jerry down the streets of New York... "You are a very bad man!!!" The End.
Just a theory.
