The over-the-top success of "Seinfeld" means Jerry Seinfeld will never do another sitcom.
He told NBC's 'Today' show, "How could I do a better sitcom than that?" Plus, he asks, "Why do something not as good?" He says the show was such a lucky, incredible coming-together of so many things.
Seinfeld also divulged that Elaine's terrible dance moves were actually based on a real NBC executive. But he wouldn't give up the name.
Seasons five and six of "Seinfeld" were released on DVD Tuesday.
