Comb Over Car

Yesterday I was out running errands and saw the driver in the car ahead of me brushing his hair forward. First I thought, hmm that's unusual, seeing a man groom while driving. And I wondered if he was working on a comb-over, since he seemed to be brushing from back to front. As I got a little closer, I realized he had no hair. So what the hell was he doing? Finally I realized it must be an electric razor, not a brush, and that he must be shaving his head. While driving. This is a new one. People. They're funny.
