The show about nothing could mean nothing but trouble if a party for its finale is held in a small park, city officials fear.

The city rejected a request by Fujifilm to hold a party for the last episode of "Seinfeld" in Bryant Park, which covers about a city block behind the New York Public Library.Police Commissioner Howard Safir and Parks Commissioner Henry Stern said Wednesday they feared the May 14 party would draw a larger crowd than the park could hold.

An estimated 12,000 people were expected to attend the "SeinFest." Dan Sieger, a spokesman for the Bryant Park Restoration Corp., said 12,000 people safely watched "Casablanca" in the park a few summers ago.
