I'm with the most amazing REDHEAD! T-Shirt

It's like, I can't believe how lucky I am to be with this amazing person who has red hair beyond description.... and I don't know the first thing about them! What planet they all come from, what the stork ate to permanently alter their hair color, whether they have parents like we do, how sensitive to water they are - does it burn them all over or just on their scalp, is Lucy their God or just a saint, why have their graveyards never been found, do they really explode if made too angry and what's a safe distance to observe this by, is it true they actually like red jelly beans, why do they always whisper "cannibals!" when we eat beets, if one of them claps with one hand when no one is around do they all hear it, etc etc? Nothing on the internet, nothing at the libraries or bookstores... I'm stumped!
