Well, on COD4, I was playing veteran on the last level, and I became so incredibly angry that I took my pocket knife and gouged my controller with it multiple times... yeah... I still use the controller though. Another incident of controller violence was when I was playing Soul Calibur 2 back in the day, I was using a wireless xbox controller, and the utter cheapness of the enemies in weapon master caused me to smash the controller against the back of my couch, breaking one side of the grip...
