A close friend of Jerry Seinfeld in the show 'Seinfeld.' He keeps all of his receipts in his wallet at all times, which in turn he keeps in his back pocket. His wallet is so massive that, when sitting down at a resturaunt, he must put a stack of napkins beneath the other pocket to level himself. Played by Jason Alexander.
