Since the humble start in the spring of 1994, The Seinfeld Index Page has grown to be the largest Seinfeld repository on the Internet. Surfers from all over the world saw the third generation of the site come to life in December last year, a change that increased traffic with around 45%.
As I write these words, The Seinfeld Index Page is closing up on 200,000 visitors since the 25th of August 1995. 65,000 of these are just from Christmas until now.
The site has an extensive collection of media clips, as well as database searching capabilities, so you'll be able to find the exact sound clip you were looking for.
