NEW YORK (CBSNew York) — Call them riffraff in a half shell.

The first winners of John Oliver’s contest to put out-of-place fans in premium Yankee Stadium seats were two young men from Westchester County dressed in Teenage Mutant Ninja Turtles costumes.

The host of HBO’s “Last Week Tonight” launched the contest this week in response to comments made by Yankees COO Lonn Trost that some fans who paid full price to sit in premium locations were uncomfortable sitting next to fans who scored the ticket for a fraction of the face-value cost from an online reseller.

“Wow! He’s saying rich people couldn’t bear to sit next to people who aren’t as rich, which would be offensive if you were talking about the opera, much less a sports whose primary fashion statement is the goatee,” Oliver joked on an episode of his show that first aired Sunday night.

Oliver then announced the show had purchased six premium seats behind home plate — two each for the first three games of this season — and was having a contest.

“There will be riffraff in those seats,” Oliver said. ” … We will sell them to you for just 25 cents apiece on one condition: You must dress like you have never sat in a premium location before.”

He asked contestants to tweet a photo of what they would wear to the game with the hashtag “#IHaveNeverSatInAPremiumLocation.”

The first winners were identified by Newsday as John Welch and Joe Spilo, of Yorktown.

In response to the Oliver’s contest, Yankees president Randy Levine released a statement Monday saying: “Everyone is welcome at Yankee Stadium. And I thank John Oliver for buying Yankees tickets.”
