I wasn't sure where to post this, but I met a guy this morning with a body modified by nature: He has two thumbs on one hand.
It appeared to be a regular thumb with a smaller nub of a thumb growing out of it - kind of like a two-headed thumb (think two-headed snake). And each thumb had a perfect thumbnail, very well manicured.
I started to ask him about it, but didn't. Now I regret it. He's obviously comfortable with it, so I should have.
What I really wanted to know is: Have you ever tried hitch-hiking with it? And if so, were you more successful than one-thumbed hitch-hikers?
