hiding or headless
That de-lurking picture is really bothering me. It's like an optical illusion. One time I look, I think someone's bending their head down hiding behind the computer with their hands on back of their head (which is what I think it's supposed to be - what with the whole quit lurking around idea). But the next time I look at it, I have a disturbing thought of a headless person sitting there with his hands folded under where his chin should be. It's really creeping me out. If he doesn't have a head, he shouldn't be resting his chin on his hands!
