Arrests Ensue After Fans Brawl over Ohio State-Michigan Rivalry on a Boat

College football fanhood runs deep—really, really deep.

While riding the Jet Express in Michigan, a pair of couples were arrested after a brawl ensued following an argument over Michigan and Ohio State.

According to 13ABC Action News, “Witnesses say the rivalry argument turned physical between two couples with a woman pulling another woman’s hair and the two men throwing punches at each other.”

Here's one rider's account of the melee:

"

They were arguing, cursing at each other. As the argument went on, the Michigan fan's girlfriend stood up, pulled the hair of the Ohio State's fan's girlfriend … the wife, actually. He tried to defend his wife by shoving the Michigan fan's girlfriend. The Michigan fan stood up and tried to defend his girlfriend. And after that they mutually started to fist fight and swing on each other. It was crazy.

"

Madness. Jet Express owner Todd Blumensaadt didn’t seem all that shocked, though.

“It happens,” Blumensaadt said. “They get very passionate about their teams. ... We haul a lot of people, bring a lot of people together. This was like 1:42 a.m., so I'm guessing there may be a few drinks involved in this one.”
