NEW YORK (WFAN) — Oh, the intrigue!

Jerry Seinfeld appeared on WFAN’s “Boomer & Carton” show Thursday to talk some football, but the conversation eventually made its way to the speculation surrounding his being spotted with Jason Alexander outside Tom’s Restaurant earlier this month.

(Refresher, if you slept through the 1990s: Alexander played George Costanza in “Seinfeld” and the Tom’s facade was a fixture on the show.)

As CBS 2’s Dick Brennan reported, Seinfeld said they weren’t filming a commercial or an episode of “Comedians in Cars Getting Coffee.” But he also said it’s “not not those things, either. It’s a secret project.”

“I gave you more now than I’ve given anyone,” Seinfeld said. “I told you what it isn’t. And then I also told you that it isn’t not that, either.”
