I found a website that has all of the scripts for Seinfeld transcribed. I think that the "show about nothing" had a lot to say about everything and this is a good resource if you find yourself searching for a quote. For instance, in one of the topics they discuss "pretzels are salty" and "not this Wednesday, next Wednesday." So, you can search for this and find which episode it was and get the exact quote. I am not affiated with this web site, but am just mentioning it so Seinfeld people can use it as a resource.
