When the Ohio State football team checked into their hotel last night prior to the 112th edition of The Game, they soon found that their room keys did not work.

Innocent mistake on the part of the staff working at Michigan hotel? Or just another day in the rivalry?

Psychological games are not new to either team in this rivalry. In 2004, Michigan players and coaches were subjected to drug and bomb-sniffing dogs upon their arrival in Columbus. And if you can believe Bob Ufer – he's a Michigan Man, after all, so it's a coin toss, really – twice during the 1970s, the water at Michigan's team hotel just stopped working while they were staying in Columbus.
