Please not that I am not endorsing this product as an alternative for domestic violence. However, if you're the type of person who needs to have something punch every once in a while, I would like to suggest the USB Punch Head.

Essentially, you plug the USB Punch Head into your computer, then smack it around. You will hear very reassuring "Owww" and "Aaah" sounds. Not only that, you can download a photo, and watch as the face contorts as you hit the USB Punch Head.

Feel free to get it on the Punch Head website sometime in March 2008.
