Go ahead and file the iTit optical wireless mouse under the, "Are You Kidding Me?" category. It is a fully-functioning computer mouse, but it looks eerily similar to a human breast.
With what appears to be a nipple that responds like a joystick, the iTit optical wireless mouse will not help the housebound geeks of the world. Better left at home then brought into the office, nothing says inappropriate quite like playing with your breast-shaped mouse.
