I still am one of the biggest Seinfeld fans around.  Proud owner of each season and I still catch it in syndication whenever I can.  Every character had their own shtick.  Cosmo Kramer, Jerry's eccentric neighbor, had a habit of making an entrance into Jerry's apartment in a crazy way.  Well, thanks to Youtube, here you can watch every entrance that Kramer ever made, in chronological order.  All 284 time over 8 seasons
