Just in time for Halloween—2007, that is—this Ghost Mouse from Pat Says Now is shaped like a mouse and has two ghosty buttons for you to click on. It's also got a scroll wheel, but face it, you're not buying this mouse for the features.
But really, what kind of person would buy this mouse? Kids? Teachers? Goths? Shut-ins? We've no idea. At least it's white, so any ectoplasm you manage to get on the mouse will be hidden from detection. And hopefully, thanks to the 800dpi laser, there are no problems with ghosting. Har har!
