Best Rodent Not Currently Residing Under Your Kitchen Sink (2008)

NAKED MOLE RAT

Bearing strong resemblance to an uncircumcised penis with an overbite, a NAKED MOLE RAT ain't pretty, but he sure is fascinating. These profoundly strange creatures are the only mammals that live in colonies like bees, run as fast backward as forward, and change physical size when moving up socially. Check 'em out at the Bronx Zoo; or if you're really bored, watch the National Zoo's webcam.
