Uncle Leo


		Uncle Leo Uncle Leo (played by Len Lesser) is the eccentric Uncle of Jerry, and the brother of Helen Seinfeld. He will yell "Jerry, Hello!" whenever he runs in to Jerry, and talks constantly. He always expects time to be made for chit chat, and is offended when Jerry leaves him on the street to go to a meeting with NBC. He also believes many of the problems caused in his life come from anit-semites. Jerry also accidently has Leo arrested for shoplifting at a bookstore. Leo often brags of his son, Cousin Jeffrey, but Jeffrey never appears in the show.
