Let's see... I've hurtled many controllers of many different consoles, I've punched my monitor (Back before flatscreens. Prol'y not such a good idea nowadays.), I even skidded a few PS games across asphalt for cheesing me off.
But my greatest rage came from when my Xbox360 got an error where it wouldn't recognize the disc, right after I got home with GTA IV back at launch, so I hucked it against the front door, shattering it.
Catharsis was had. Then, the most wonderful thing happened. My wonderful wife actually put it back together and fixed it! She's awesome. Things she's fixed in the past include, but are not limited to, controllers, cars, washing machines, vacuums, computers and furniture.
I call her my Baby Fix-It. ^_^
