Warning, because the photo below contains profanity

One of the most bitter rivalries in sports—-Michigan vs. Ohio State—-will once again have a say in college football's national championship picture when the two sides square off Saturday.

That intensity obviously extends to the schools' student bodies, one of which made clever use of some dormitory lights to send the other a rather pointed and derogatory message.

The ball, as they say, is now in the Buckeyes' court.
