Known as the Flannel Fun Guys, the quartet, which occasionally calls for substitutes, can often be seen in the first few rows of the Izzone, cheering and heckling the rival team.

“We knew we wanted to do something for a while, but we didn’t know what,” said Mooney, a psychology junior. “There have been a bunch of famous costumes in the Izzone. We just wanted to do something silly, and we said ‘let’s just do flannel.’ It hadn’t been done before, it’s original.”

The group’s outfits consist of green flannel shirts, glasses without lenses and MSU hats. The Flannel Fun Guys cheer and chant along with the other Spartans — with their added heckling.

According to Mooney, there is significance behind the costume.

“We took some of the frat glasses, and popped the lenses out, so we turned those into hipster glasses,” he said. “We all wear hats too, so just (kind of) making fun of the whole hipster idea.”

Mooney saidas a group, they don’t consider themselves different from other members of the Izzone.

“Everything that the Izzone does as a whole, we do,” said Mooney. “We try to research some of the opponents before the game, try to find a little background information on the team, players, their girlfriends, moms, what have you.”

Ellsworth, a political theory and constitutional democracy junior, claimed their objective is to make the opposing team’s job as hard as possible.

Zingg, a chemistry junior, said through the groups efforts in the Izzone and on Twitter (@FlannelFunGuys), they have become popular.

“We’ve gotten a lot of response of Twitter,” he said. “People tweet at us and say ‘Hey, I see you guys in the Izzone.’ And they’ll snap pictures, and when they see us on TV they say ‘Oh, I see the Flannel Fun Guys.’ That’s cool.”

And the attention extends beyond campus. Zingg said they often are shown on TV during games.

“It’s pretty easy to pick out the flannel among all of the white,” Zingg said. “It’s pretty easy to see. Plus we typically get there pretty early, so we’re in the first couple rows. We’re always on camera.”

Ellsworth said the group hopes to be shown on the Big Ten Network show “The Journey.”

“Last year they did (a feature on the) Illinois fan section,” he said. “We want to represent the Izzone in that.”
