Best Zoo Animal - 2003
Readers' Choice: Monkey
The name alone will bring merriment to grade schoolers and socially stunted adults worldwide. But this miniature mutated antelope's god-awful territorial habits ensure its place in the Kick-Ass Mammal Hall of Fame. Not much larger than a hare, the male of this African species has a scat fetish so bizarre, it'd make G.G. Allin spin in his grave. Like other critters, this antelope aberration marks its territory with heaping piles of dung, but with a twist: The male dik-dik will paw through the female's feces, then add his own on top, urinating at the same time -- just so outsiders get the point. By the way, they actually say "dik-dik" when they're startled. Yes!
