You know, its kind of funny. My favorites have, for the most part, been redheads. But, every time I have had girls almost fight over me when I was young, where blondes vs brunettes (yeah, I know I was an idiot for stopping them, but I was young and I didn't want someone REALLY getting hurt. And, there was a very real chance of someone getting hurt in each case.).
In most cases I would have given the edge to the brunettes to win.
