I've always been curious as to why evolution would have caused man to LOSE his hair, which would seem to be a distinct disadvantage as then man would have to waste time and resources to provide for himself coverings to protect against the elements. You'd think that the ones that didn't have to expend the extra energy to do that would have more time to find food and thereby increase chances of survival. Not to mention, not dying from exposure.
If we had all that hair, what would be the fun in getting nekkid?
Naked vs. Nekkid as defined by the late great Lewis Grizzard.
Naked: You have no clothes on.
Nekkid: You have no clothes on and are foolin' around.
