.....i was thinking about something, more "Pavlovian".....
.....like metal keys on the keyboard connected to the negative side of about 20 serried 12volt batteries.....
.....and the positive connected to, lets say, their (lack-of) manhood.....
.....maybe every time they saw a keyboard after wards.....
.....they would begin to sweat, breath hard and pass out.....
.....(but that's just the sick kind of guy I am).....
