Jerry Seinfeld – America’s biggest comedian and most probably the Mets’ most successful fan – has condemned the behaviour of the Citi Field crowd, comparing them to five-year-olds as they booed players at the 2013 MLB All-Star Game.

Talking to New York’s WFAN radio on Wednesday, Seinfeld said: “This is one of the lowest moments of my lifetime of Mets fandom, when the Citi Field crowd was booing (players) that they see as rivals to their Mets team.” He told Steve Somers: “And I’m standing there, I was in shock. I was embarrassed. I thought it was horrible manners.”

Seinfeld - alongside Larry David - created the ‘show about nothing’ - which became America’s favourite sitcom. Including elements of situational comedy before it, it would equally influence those that proceeded it. The show ran for nine seasons and provided the platform for David’s Curb Your Enthusiasm.

Watch the classic 'Nice Game Pretty Boy' scene from Seinfeld:

The comedian continued of the ill-behaved fans: “These are the best players, in the game you love, that have come here to put on a show for you, and we’re booing them like 5-year-olds. As if there’s some sort of real animosity... The American League is not the Taliban. What are we booing Miguel Cabrera (for)?... So I was very embarrassed by that.”

Jerry, born in Queens, was in impressed with the way the fans treated the farewell of Mariano Rivera, however. “I felt redeemed by the reception that we gave Mariano Rivera and that brilliantly staged farewell.”
