Okay, here's one for all of you to consider. My hair is three different colors (not counting the gray that is creeping into the beard, temples, and where the little fine hair grows where the rest has receded, making a beeline for my behind): blonde, brown, and red.

The real stumper is that my eyes change color. On any normal given day they are blue or grey. When I get really angry, they turn green. The effect is frightening to watch, I've been told. (Please limit your Incredible Hulk references, It's only my eyes that turn green.)
