ThinkGeek has a proud history with April Fools' Day gags, even going so far as to make one of its jokes into reality after it snowballed in popularity. This year, the gang is pretty much guaranteeing that won't be the case with its super-exclusive Wii title ... Super Pii Pii Brothers. And yes, as you've probably already guessed, it's a game about peeing on cats. They have a ton of other great gags you can check out here.
We've put the video for it after the break. We're not sure if it's NSFW, but we hope you work in a place where this sort of thing isn't acceptable. Unless you're that "Two Girls One Cup" guy, then this is the height of érotique.
