Humans have two thoughts about mice. We either find them adorable (Mickey Mouse, Jerry from 'Tom and' fame), or we want to hit them repeatedly with a broom. Generally, there is nothing else, which is a shame. Why? Because as it turns out, these little critters can be pretty amazing, even in non-cartoon form. Case in point, the mice in this video. They play basketball, ride skateboards, do the 'fetch' thing, and pretty much just spend most of their time geniusing up the place. To boot, they were trained through positive reinforcement only, which should make the folks at PETA slightly less whiny about the whole thing.
