It's always puzzled me why people have hair on their butts. If you look at other animals, they have hair everywhere EXCEPT their butts. I just can't seem to piece together the genetic/evolutionary advantage of hairy butts...it sure doesn't serve a purpose now.
Imagine how much cleaner you could pinch a loaf if you didn't have all kinds of things for said loaf to deposit itself on. In fact, with hairless asses, we could just about eliminate the need for toilet paper. Not to mention that the hair's unsightly.
