Jerry Seinfeld joins Mets broadcast booth (VIDEO)

If you don't already get enough of "Seinfeld " reruns airing non-stop on television these days, maybe you were lucky enough to catch real-life Jerry calling the Mets game at Citi Field Tuesday night.

The star of the iconic TV sitcom and die-hard Mets fan joined old friend Keith "Pretty Boy" Hernandez, Ron Darling and Gary Cohen in the SNY broadcast booth during the game against the Giants.

The comedian brought his usual sense of of the absurd to the quartet and offered a few What's the deal with takes on things bothering Mets fans (maybe not) these days. Seinfeld suggested padding the outfield walls with sofa cushions to make them safer and getting complimentary surgery for mentioning Dr. James Andrews on the air. He even touched on Hernandez's make-out scene with Julia Louis-Dreyfus on the classic hour-long 1992 episode "The Boyfriend." Hernandez sounded joyful recalling they did the scene in "eight takes."

As hopefully expected, it was a broadcast segment about nothing. Not that there's anything wrong with that.

12 year-old calls plays from Mets broadcast booth like an old pro (VIDEO)

If that voice you heard calling plays the New York Mets broadcast booth Wednesday night didn't sound like SNY regulars Keith Hernandez, Ron Darling or Gary Cohen — you are correct.

The new play-by-play announcer was no veteran but a "kidcaster" who had practiced in front of a basement TV in his Long Island home before his big moment.

Twelve-year-old Johnny Gadamowitz may have sounded like an old pro and knew Mets history, when he took the mic just as pitcher Matt Harvey came up to bat against the Colorado Rockies, but he was just filling in at Citi Field as a contest winner.

"I wish he could get in some more wins," he said of the starter Harvey. "He gets too many no decisions."

For five minutes during the bottom of the second inning, Johnny called the plays with the Mets' regular broadcasters and both Cohen and Hernandez were impressed the boy's memory and joked that he could take over for them.

 Young Johnny won the gig with an essay in the annual kidcaster contest held by SportsNet New York, the TV home of the Mets.

In a 100-word essay on what he most enjoyed about watching the Mets, Johnny said it was being with his grandfather — a Mets fan ever since the Dodgers left Brooklyn. It was in front of the television, many times with his grandfather, that Johnny decided he wanted to get into the sports and media field.

"When I was doing the play by play, it was a really fun experience," he said of his exhilarating stint in the broadcast booth, "but I was at the same time trying to think of stuff to say so there wasn't any dead space."

Ah, dead space — the bane of all broadcasts.
