I have to say, playing for the Purple Hurricanes was fun, until I realized the association most people made with purple. It was never easy to wrestle or play football in purple; of course, it did make soccer easier.
On another entirely useless and at best mildly amusing note, the bulldogs were originally the goats, but they became U[sic]GA bulldogs after years of inter-species inbreeding and getting thumped by Yale back around the turn of the 20th century. Either that or their fans got tired of seeing their wives paraded as college mascots.
Truth be told, I like most of the mascots on the list, including the Stanford tree. Any mascot that gets drunk and causes havoc in a fashion which poses no harm to others is alright by me. Nothing tops the Leland Stanford Junior University Marching Band.
