Interesting idea.
Going on what someone in my office says half the time he sees me (the other half is surprise at running into me unexpectedly), probably a younger Butch Patrick, who played the character "Eddie Munster" on The Munsters during its run from 1964 to 1966. He says I remind him of the character from the show (which I'm not sure is such a good thing, since the kid resembled a werewolf-or maybe it is just the hours I keep).
I also get a lot from other people who say that I look like someone they've seen on TV (no, not at the post office), but they can't recall who.
