Ahem. The proper name is:
Moo U!
I was out playing tourist this past weekend, saw a lot of T-shirts. The most popular seemed to be "My 2 favorite teams are Michigan (U of M, for those of you in Rio Linda) and whoever beat State" and "Friends don't let friends be fans of State". Yes, I found the ones that were pro-State (as am I), but those weren't as prominently displayed!
