that happened to my old GCN controller. After a year and a half of faithful service, it started doing that. I had to hold X, Y, A and Start more times than I care to remember.
i remeber i had a broken clock above the TV in my basement. the second hand would just kinda shake , go forward then backward reel quick each second. and my friend and i were playing a game and we got mad at it for some reason so i just sat back in the sofa. just casually picked up the controller and chucked it at the clock. it nailed the clocked and the clock fell off the wall hit the TV and fell onto the ground. when i went to pick it up to put it back it was working. we started crackin' up. my controller worked to. just to show u everything made by nintendo has a dual purpose.

LMAO good story, also proves the durability of Nintendo brand products XD.
