"Characters" at Univ of Washington Seattle

Have you ever noticed the guy that walks around campus with the tail and the ears? Is he a furry?

It seems that UW has some funny characters and factions. Like the Tails guy, or the croquet people, or even the 'boffing club'. Whatever happened to those crazy duct-tape weapon wielders?

I suppose there are more characters that I haven't yet had the time to meet, but do you have anything to add?
