Yep... I broke like 2 or maybe 3 in my whole life... I had really bad anger issues, but that's what I get for having really severe ADHD. I would throw my controller at the TV (they were tube tv's back then), but they wouldn't break, but after doing it multiple times, they broke... I've matured a lot since I was little. Sometimes, I did trip on the cord though or accidentally drop them. I have one that the one of the analogs are messed up but the controller itself still works and I can still use the D-Pad on it.
I did have one Xbox controller (the original Xbox) that was white and I ate Cheetos one time and I couldn't get it off the controller and the wire got a loose connection and it would work sometimes, but years later, all of it came off and it still does it, and I still have it... I actually have all the controllers I broke. Another controller I have is really sticky and still works and I use it for my PSX and PS2 and another one that the wire is hanging out on it (these are PSOne controllers, the really bright white ones), but it still works. Actually, I think all of them work, but they just act funny sometimes. I don't think I have 'broke' a controller that actually does not work and respond before.
