Reminds me of a guy I used to work with. He wore earbuds because, so HIS story goes, outside noises really distracted him when he was doing his tedious numbers crunching. We all knew he was watching football but went along with his story. One day after sitting at his desk quietly for a while, he jumped up, knocked his chair over, and yelled, 'Run, dammit, run!' It was hilarious....and I laughed out loud at your description, too.
