Well, this is kind of upsetting. Along the same lines as that super-creepy beaver computer that we showed you a little while ago is the Mouse Mouse. Yes, it's a computer mouse made out of an actual mouse.

This is actually worse than the beaver computer because with that at least you weren't expected to keep your hand on the dead animal all day. Can you imagine having your hand on a dead mouse all day at work, clicking the back of its poor head every time you need to open or close a window? It gives me the heebie-geebies. But hey, if you're a more cold-hearted, sadistic person than I am, there are plenty of instructions on how to make one yourself. Sicko. — Adam Frucci
