Now, Seinfeld is considered an elder statesman of comedy and has a successful Web series, "Comedians in Cars Getting Coffee." An ad with former co-star Jason Alexander aired during the 2014 Super Bowl and furthered speculation that a "Seinfeld" reunion might be in the works. Sony Pictures Television

While Alexander hasn't snagged a permanent weekly gig, he is apt to show up in any number of shows, like as "Mountain Man" in an episode of "Community." Justin Lubin/NBC/NBCU Photo Bank/getty images

Richards ran into some tough times in 2006 after a rant at one of his comedy shows included some racial epithets. But he has bounced back. In 2013, he could be seen on the TV Land series "Kirstie," starring Kirstie Alley. Evans Vestal Ward/TVLand

Since 2011, Knight, shown here with David Alan Basche, has had a role as Haskell Lutz on the TV Land series "The Exes." Evans Vestal Ward/TVLand

Harris has stayed busy acting and doing voice work, including roles on the animated series "Futurama" and the voice of Mrs. Potato Head in the "Toy Story" franchise. Tibrina Hobson/FilmMagic/getty images
John O'Hurley was often the butt of the joke as J. Peterman when he teamed up with Louis-Dreyfus. Joey Delvalle/NBC/NBCU Photo Bank via Getty Images
O'Hurley has remained popular since the end of "Seinfeld." He was a contestant on "Dancing with the Stars" in 2005, and he was host of "Family Feud" from 2006 to 2010. He also has been host of the annual National Dog Show Presented by Purina. Bill McCay/NBC/NBCU Photo Bank/getty images
