For the New York Mets minor league baseball team, the Brooklyn Cyclones, this past Saturday was the biggest day of their year.

It wasn't opening day, or a game against a rival, it was Seinfeld night.

"This is always our biggest night. People care about this more than opening day, more than any other game during the season," said Billy Harner, Brooklyn Cyclones Assistant GM.

Harner said that because players are always getting moved around the Mets farm system, the Cyclones have very little control over the team on the field.

What can they control? The atmosphere of the game.

That is how the idea for Seinfeld night started in 2014.

Harner said he didn't know how the promotional night was going to go, but it was almost immediately apparent that Seinfeld night was going to be a hit.

Every year people pilgrimage to Coney Island where the Cyclones play.

They wear Seinfeld shirts and hats, they talk about the show and most importantly they wait in line and get a Seinfeld bobblehead.

Bobbleheads all over the country have become very collectable, and no bobblehead may be more desired than the yearly Cyclones' Seinfeld themed bobblehead.

"Our Seinfeld night bobbleheads is, I've really never seen anything like it before, people line up hours in events. Today every fan was guaranteed a bobblehead if they walked through the gates. They were guaranteed a bobblehead and people were still here 3 hours before the gates opened to make sure that they were one of the first to get it," said Harner.

Inside the game, bobblehead resellers covertly approach people and offer to buy the bobbleheads from people.

Elizabeth Tripp was barely in the stadium when a man approached her.

"A guy offered me and my sister $20 for it . He said he was a big Seinfeld fan, the biggest ever," said Tripp.

Tripp said that this years bobblehead, of the famed Kramer painting in the show, didn't get her excited so she sold her bobblehead to the man filling his back with as many as he could buy.

The bobblehead may be what gets many fans in the gate, the Elaine dance off is what gets them to stay the whole game, and then some.

"The Elaine dancing contest and seeing people stand around and sit here for 25 minutes, half hour, 45 minutes after the game ends, watching 20 women dance poorly and cheering their minds cheering out of their minds," said Harner. "It's the best part of what we do and it really makes you feel like you're hitting a home run. Sorry for a baseball pun, but you know that's what we aim for every night, making sure people are having a good time regardless of what happens on the field."
