NEW YORK (AP) _ What's in a name?

Plenty, NBC learned Thursday, as ``Seinfeld'' readied to reveal the first name of Kramer, Jerry Seinfeld's eccentric neighbor.

Kramer (Michael Richards), known for his high-stacked pompadour and explosive style of entering a room, has been known only by the single name since the top-rated show debuted in 1990.

Fans have asserted since the episode was filmed in early December that Kramer's first name is Cosmo.

But the network refused to confirm or deny it, despite a deluge of calls from reporters.

``I can't remember receiving so many inquiries about a single subject since Johnny Carson went off the air,'' said NBC spokesman Curt King.
