Jerry Seinfeld knows something we don’t.

During a stand-up set in Boston on Saturday (Oct. 7), the comedian was asked by members of the audience if he liked the ending of Seinfeld, the NBC’s hit “show about nothing” he starred in for nine seasons.

“The ending of the show?” he asked, per a video posted to X and reported by Variety. “Well, I have a little secret for you all about the ending.”

However, he said he “can’t really tell it.”

“Here’s what I’ll tell you, but you can’t tell anybody” he continued. “Something is going to happen that has to do with that ending.”

While he revealed that nothing has happened quite yet, he teased that he and series writer Larry David have been in cahoots on their secretive surprise.

“And just what you are thinking about, Larry and I have also been thinking about,” he said. “So you’ll see.”

Not everyone was happy with how the two-part finale played out in May 1998, which wrapped up with the show’s principal cast of characters — Jerry, Elaine (Julia Louis-Dreyfus), Kramer (Michael Richards), and George (Jason Alexander) — being locked away in jail for a year-long sentence.

According to The Guardian, Seinfeld himself even had some regrets over the series finale. In an interview at the October 2017 New Yorker Festival, he said, “I sometimes think we really shouldn’t have even done it.”

“There was a lot of pressure on us at that time to do one big last show, but big is always bad in comedy,” he added, noting that comedy should be “small and cheap and quick.”

In 2018, Seinfeld appeared on The Ellen DeGeneres Show and told DeGeneres that a Seinfeld reboot was “possible.”

According to Variety, the secret could align with David’s Curb Your Enthusiasm, which has yet to announce a release date for its upcoming Season 12. If so, this wouldn’t mark the first Seinfeld reunion to take place on the show. In 2009, the four Seinfeld stars reunited on Curb‘s Season 7 finale, per Entertainment Weekly.

Seinfeld is streaming on Netflix.
