I do not, but I am multiracial and there just aren't a lot of people that look like me to begin with! I've seen some people that really make me do a double take, though, because they look so much like friends of mine. And when I got my hair cut in Disneyworld the guy doing it looked like Kenneth Branagh, which was kind of neat.
In my younger days... in my early teens my celebrity Doppelganger's were Danny Thomas or Ringo Starr by my peers and I was always called to by those names. I use to have a big nose and a Beatles style haircut and because I wore no make up I looked like a guy. It wasn't until I had cosmetic surgery and started wearing dresses that nicknames finally faded away.
