Watch the "It's Not a Reunion, but It's The Closest You'll Ever Get" promo for the Seinfeld on the next episode of Curb Your Enthusiasm, entitled, The Reunion.

In the episode, Jeff pitches the idea of doing a Seinfeld reunion to Larry, who refuses at first, until he realizes how he could make it pay off personally.

Three of the four stars of 'Seinfeld' have made guest appearances on 'Curb Your Enthusiasm' over the years. In Season 2 both Jason Alexander and Julia Louis-Dreyfus appeared as themselves when Larry was pitching a new TV show. And in Season 4's finale, Jerry Seinfeld appears, wincing in the audience of 'The Producers' when Larry forgets his lines.

This season, Jerry Seinfeld, Julia Louis-Dreyfus, Jason Alexander and Michael Richards all appear as themselves. In real life, they've all denied any interest in reuniting. What changed their minds? Stay tuned...

Curb Your Enthusiasm stars Larry David, Cheryl Hine, Jeff Garlin, Susie Essman and in the upcoming episode Jerry Seinfeld, Julia Louis-Dreyfus, Michael Richards and Jason Alexander.
