Jerry Seinfeld teases 'secret project' with Jason Alexander, other 'Seinfeld' alumni

Remember that photo of Jerry Seinfeld and Jason Alexander taking a stroll past the iconic New York diner they once frequented on "Seinfeld"? Well, while most of the mystery about that meet-up remains, Seinfeld himself teased a few details about it during a radio interview with WFAN's "Boomer & Carton."

And the biggest detail of them all? Alexander isn't the only "Seinfeld" star who joined him for the ... whatever it is.

In addition to confirming the presence of other "Seinfeld" regulars (including co-creator Larry David, who took on an off-camera role for the event), the funnyman cleared up rumors that it's all for a Super Bowl ad or maybe the latest installment of his Web series, "Comedians in Cars Getting Coffee."

"It's neither," he said before blurring things further. "But it is not not those things, either. It's a secret project."

So maybe it's both a Super Bowl ad and an installment of "Comedians in Cars," then? Who knows? Not the guys from "Boomer & Carton," that's for sure.

"I gave you more now than I’ve given anyone,” Seinfeld said when they balked at his answer. "I told you what it isn’t. And then I also told you that it isn’t not that, either."

Clear? Well, no — and that's just how he wants it.

But Seinfeld did reveal that the "short-ish" (but longer than 60 seconds) project was filmed at more locations than just the diner, and best of all, that we'll have a chance to see it "very, very soon."
