My brother and I decided that we would root for Peen State at the Orange Bowl a few years ago because the PSU fans were so much friendlier than all the FSU fans.
We got a bit tired of the whole WE ARE.........PENN STATE bit though.
Anyway, my brother saw someone wearing a PSU shirt not too long ago on the Illinois State campus and he challenged them with a "WE ARE" shout. They had no idea how to respond to him, so we decided that there are a bunch of weakassed PSU fans out there. Whether his conclusion is accurate or not, I don't know, but if you don't know the whole 'WE ARE' bit, what the hell are you doing wearing the school colors???
