Do you believe the presumption that we all have a double somewhere? Behaviorally, mine is apparently in Asia:

I don't know where mine is. :  (

I have met mine. When my kids were in elementary school, the new principal was walking down the hall and the students were addressing him "Hi Mr. (my name)". He was obviously confused until someone told him he looked just like me. (The students there all knew me.) A couple of years later, while I was working the concession stand at our HS football game, he came to to get a drink and a hot dog. We both did a double take. It was like looking in a mirror. I had more gray hair than he did. Years later, one of my colleagues said he saw me walking down the street in a small town outside Toledo and called out for me. It was my double.

I'm sure I've got a doppelganger out there somewhere.  If you thought having one of me was bad, just imagine there being two of me.   I'm sure just the thought of it would put Randy in a comma coma.
