Doppleganger

I was listening to Penn Jilette's podcast (http://penn.freefm.com/), and I heard something that crushed me. He was talking about how every tall, overweight, block-headed guy wearing glasses and a ponytail that comes up to him tells him that everyone thinks they look alike. And he agrees. They could stand in for him on stage, and no one would notice. (the audio file is here and it starts at 37:23) I think it's time to get rid of the ponytail and get a hasselhoff.
