Heh. Yeah... I'm 99% Northern European/British Isles (this includes the Neanderthal) but we found a 1% Sub-saharan explanation for my butt.

Big butts abound throughout this earthly orb. No culture corners the market on them. I lived in the middle east five years and saw SO many humungous butts--LARGE female Arab butts! Wow. I felt like Skinny Minnie and I AIN'T! :O)
