Yeah, USC dominates Southern California...but that is because they have had the most recent success. When USC sucked (all through the 1980s and 1990s) USC fans were nowhere to be found and you couldn't swing a dead cat without hitting someone wearing a Troy Aikman UCLA jersey.
So Cal fans are a bunch of front-running, bandwagon, A-HOLES who know nothing about college football. It is truly annoying. Whenever some USC "fan" starts spouting off about how great USC is I have a sure fire way to shut them up. I ask them to name five current players. I swear, I have yet to say that to someone who could come up with just five. Just for fun sometimes I expand it and say: "Name any five players who have EVER played at USC". 9 times out of 10 they can't even do that. Great "fans".
