Man, end of the 2nd page and there aren't very many that have broken the things. Well, I'll fess up.
An old habit since is for me to hold the controller in my right hand and slam it down on the footrest of my foldable, reclining chair. Usually, this means hitting some canvas. However, 1 DC controller and 1 GCN controller have met the metal cross bar that supports the footrest. The DC controller cracked on the left side, and the analogue stick stopped working properly. The GCN controller looked fine, but the analogue on one of the shoulder buttons gave out. The full click still worked. I'll add that fittingly enough, I was playing Smash Brothers at the time. Yeah, I make a point of not doing that anymore, since today’s controllers can't quite take it.
As far as total losses on controllers, there are the two above, my included N64 gray controller was taken in my dorm, my included PS2 Dualshock was stolen out of my dorm (separate occasion), and I think I have two malfunctioning PS2 controllers that I never use (seriously - [/i]never) that I think got screwed up by bastards at my crap dorm [anger]. I also have a strange Xbox Controller S. The A button and the white button are crossed, so they do the same thing. It's sort of funny as a joke or a handicap - give it to the best Halo player in your group, and the flashlight will turn on and off every time they jump.
My roommate's a real dick about breaking controllers. He decides he's going to break it and smashes it on the ground. But what does he care? He just switches it out at Wal-Mart. Asshole.
