They have those toys that you can get to mount on your dash. Road Rage Eliminators / Audio Stress Relief basically. They have buttons marked "grenade" "machine gun" "laser beam" and so on. It would certainly be funny to load mp3s or wavs of various stress relief noises, and then assign various trigger buttons to them. For example, get a generic remote and use hijack to assign buttons to various sounds and use that remote to activate the noises! :-D

How cool is that?
