I can bet his co-workers hate him.
So at work I occasionally listen to music through headphones (don't worry, they do a good job of keeping the sound in and I make sure the music doesn't leak out and annoy coworkers etc. etc.). When I wear my headphones, the headphone wire hangs on the right side of my office chair's arm. When I put my headphones back on my desk, the wire loops around the left side of my chair's arm. When I roll my chair away to get up, the wire catches and my headphones clatter to the floor. EVERY. GODDAMN. TIME.
