Almost Ultimate Seinfeld Character Quiz with Initials, Categories, and Oddball Characters
Initials are given for these characters, which are also loosely grouped into categories (some characters overlap categories). How many can you name? Note: This quiz only lists characters who were given first and last names and is pretty inclusive, but does not contain every single name uttered in all nine episodes. :)
good job, although I don't know about including characters that were mentioned but never appeared on the show (JFK Jr, Castro, Hussein, etc). Also maybe add Regis and Kathie Lee, who interviewed Kramer about his coffee table book.
