VIDEO: Ohio State players get locked out of Michigan hotel rooms

This was either a crazy coincidence, or a perfectly executed prank.

On the eve of the Ohio State-Michigan showdown at the Big House, Buckeyes players went to check into their Ann Arbor hotel.

There was only one problem: their key cards didn't work. Not just one or two of the players, but every single one of them.

Here's a video of the team standing in the hallway wandering aimlessly.

The Wolverines clearly got the first laugh.
