Someone (link now fixed) took this too much to heart.

"From Dictionary.com:
bear (bâr) n.1. a. Any of various usually omnivorous mammals of the family Ursidaethat have a shaggy coat and a short tail and walk with the entirelower surface of the foot touching the ground.
b. Any of various other animals, such as the koala, that resemblea true bear.
So the koala's resemblance to a "true" bear indeed makes it a bear! NYAH! :P"
