In high school, I was a Knight. As an undergraduate, I was a Cougar, an Eagle, and a Buccaneer. In graduate school, I was a Nanook, and then I was a Cougar again (different school, same mascot). As a professor, I was a Panther, and for the last 11 years, I've been a Raider.
I like being a Raider. Being a Buccaneer was good training for becoming a Raider; I guess there's something about "raiding", especially if you're playing an away game. And I'm happy not to have an animal as a mascot, because animals make for weird bobble-head dolls.
