i used to wonder the same thing when i danced... guys would always go for the blondes over the other colors even if she was a dog face... maybe they are afraid of the "fire in the hole"
I did an experiment on halloween once ( I used to sport some serious red hair) and dressed as "marilyn monHO" with a blonde wig. I had guys asking for dances left and right.. guys who were regulars and knew me and never danced with me before..and all because of the fucking blonde wig..pissed me off
