Having your pointer move against your will feels incredibly wrong. I used to us this to my advantage in the computer lab, by plugging in my mouse to my classmates' computers and screwing with them. Once, I was chatting with my buddy, looking him in the eye, all while fumbling around plugging my (wired) mouse into his desktop's USB port. It just didn't register with him, and a few minutes later I just started subtly messing with the movement of his cursor. Good times.
