Someone broke into my car once, they smashed the rear window, crawled in, and took the knobs off my stereo. Apparently they couldnt figure out how to get the stereo out of the dash, it was just shoved in there. So then I had to buy these crappy auto parts store type replacement knobs, and whenever I turned the volume up, the balance went all the way to the left. A couple of months later the left channel died. Assholes.
