I guess in this case I should say "celebrity."
TWO - count 'em, TWO - separate people in Las Vegas mistook me for all-time Jeopardy champion Ken Jennings this weekend.
A couple of people I know mentioned to me at the time that we (sort of) favored, but no one had ever mistaken me for anyone before.
I got "you look like that guy in that movie" (turned out to be Paul Bettany) from a waitress a few weeks ago. Not that it would be so bad to be hooked up with Jennifer Connelly, but...
From now on, I'm going to say, in an accusatory tone, "What? All blond-haired, pale white guys look the same to you?" Then I'm going to go in to the Jazzman routine and talk about how hard life is for people like me.
Anyone else been mistaken for a celebrity?
