In all reality this product could just be a shipment of little, plush stuffed characters that fell off the truck and were hocked as screen cleaners, but I'm pretty sold on 'em. Mickey and Minnie's stomachs are actually soft, optical grade fabric cloth that can clean your screen by humping the shit out of it. Both of these are available for $10.

Edit: Speaking of Mickey and Minnie Mouse humping, hit the jump to see an awesome video courtesy of our hombres at the Consumerist. It could be NSFW, if you work at a church or something, but it is pretty tame.
