"Hmm.. ISTR a BOFH episode where the ENTER or RETURN text was actually a series of conductive tracks, giving decent jolts to anyone using it.. Wonder if I can rig something similar to some of these user's mice. Click the wrong thing, get a virtual slap on the hand - with real pain and (if the jolts are fun enough) real loss of bodily control!"
But then you meet your match with a masochist. Pain gets him off.
