I thought he was joking, but now I'm not so sure. I've seen the horns myself, now! Being the metrosexual guy that he is, he manscapes, he uses hair product, he dresses well. His hair pretty much always gets some product after he showers to keep his "jewfro" (his term) under control. But a few times now, I've seen his hair without the fine control of whatever he uses to wrestle it into a perfect coiffure... like this morning, when he got out of bed and puttered around for a couple of hours before hopping in the shower. And I've realized that the natural tendency of his hair, when he's not wrestling it under control with hair product, is to form little horns. Seriously, when uncontrolled, the hair at the top of his head (which is no more than an inch or two) naturally forms itself into little horn shapes, as if he TRIED to do that.
Yep, he's just a little bit evil. And I like it!
