Despite five consecutive nominations (1991-1996) for playing a version of himself in his iconic self-titled comedy, Jerry Seinfeld never took home an Emmy for acting. The show itself, however, won for Outstanding Comedy Series in 1993.

Jerry Seinfeld, Jason Alexander and Larry David filmed an unknown project inside the restaurant that served as the inspiration for the NBC series' iconic diner.

Jerry Seinfeld, Jason Alexander and Larry David had a Seinfeld reunion on Monday at Tom's Restaurant in New York, the exterior of which was pictured as the outside of Monk's Cafe on the NBC sitcom.

Seinfeld and Alexander were spotted walking outside the restaurant, with Alexander wearing a particularly George Costanza-like outfit.

But why did the famous funnymen get together? Camera equipment was spotted inside the restaurant, according to a report on Gothamist, which confirmed that Tom's was closed for a few hours on Monday and pointed out that there were cables shown going into the restaurant and the shades were down, in addition to the cameras inside.

Some of the equipment said "Comedians," suggesting the trio was filming one of Seinfeld's Comedians in Cars Getting Coffee episodes, but maybe they were shooting something else, like a Super Bowl commercial.

A rep for Seinfeld said he couldn't tell The Hollywood Reporter what they were filming, while Alexander's rep declined to comment.
