This issue has been something of a recurring point (though not a terribly frequent one) on The Best Show for some years.
Surprisingly, I usually ended up on the receiving end of some flattering comparisons. But age and self-abuse are tremendous equalizers and as the years have gone on, the comparisons have gotten less and less flattering.
Two Thanksgivings ago, I was at my father's place with the rest of the family, who are a very free and easy lot (particularly when the drink is flowing). We were having whatever fun-n'-filthy conversation we were having, when my uncle turned to me and said, "Do you know who you look exactly like with those glasses?"
I immediately halted him and began to deliver the Scharpling theorem on such conversations. My uncle, however, was having none of it, and the conversation devolved into a semi-restrained argument about the issue until he forced his way through the matter by proclaiming, "I just think you look exactly like Jamie Hyneman," the walrus-moustachioed, beret-wearing question mark from "Mythbusters".
We all got a laugh out of that one -- myself included. Still, I was not pleased.
