quick question

how come blondes still have dark eyebrows?

oh and also I don't really watch much TV but I've had a lot of time to kill while I've been sick and I noticed that a lot of celebrity women and models wear really low cut dresses and crosses. Not that I neccessarily mind or find it to be hypocritical, I just kind of wonder, why a crucifix? Is it because God likes to be near a great pair of boobs?
