The football teams aren't doing much talking, but the fans don't seem to mind.

The first bout of Michigan-Michigan State rivalry hijinks apparently took place either late Tuesday night or early Wednesday morning, as The Michigan Daily's Alejandro Zuniga spotted green spray paint over the block 'M' on the University of Michigan diag, which sits in the heart of campus.

The letters "S" and "U" follow the "M." I think most can figure out what that spells.

Michigan heads to Michigan State on Saturday (3:30 p.m., ABC). The Spartans have won five of six in the series, and opened as a 15-point favorite.
