We've all suspected for some time that Homer Simpson doesn't have a great deal in the upstairs department and now we have scientific proof in the form of this background wallpaper.
Install this onto your phone and you can show everyone just how tiny Homer's mind actually is (it's not much bigger than a pea). It's a cleverly drawn x-ray image showing a side profile of Homie's head. It's pretty funny and the fact that the background is largely black means it doesn't hamper your view of the phone's icons.
An essential download for fans of America's favorite family.
