Funny story from quite a few years ago, I work for a county repair facility and the shop supervisor wouldn't allow us to have a radio on. I started wearing those old headphones that were a radio (read: RADIO, not an Ipod since they were someones dream back then). One day the county safety guy came into the shop and saw me. It wasn't long after that we were allowed to have a radio on because the headphones were dangerous in that you couldn't hear what was going on around you in the shop. I guess I won that one!
