Seinfeld cast

9 of 13
Seinfeld, the self-described "show about nothing," was one of the most popular sitcoms on television during it's nine-year run. The credit goes to the talented cast, who reunited on Oprah's stage in 2004: Jerry Seinfeld, Jason Alexander, Julia Louis-Dreyfus and Michael Richards.

The show's humor and originality worked its way into our vocabulary with Seinfeldisms like "yada yada yada," "close talker," "sponge-worthy" and "master of your domain."

It was the end of an era in 1998 when the last Seinfeld episode aired and was watched by 76 million people. Before their last-ever taping, Jason said Jerry had a few words for the cast. "He said, 'For the rest of our lives, when anyone thinks of one of us, they'll think of all four,'" Jason said. "And then added, 'I can't think of three people I'd rather have that be true of.'"
