LOL, yes, that's been suggested; believe me, we've been over just about every imaginable reason for wearing clothes.
Still, I think we're in agreement that a lot of shock value (and a possible arrest) would result from someone disrobing out on some public street (even if it was a warm day). So what probably started out (in the Ice Age) as protection from the elements, somehow evolved into the complex rules about clothes that govern human behavior today.
Hasn't been brought up for awhile though so good point; good timing too I think ...
Love means never having to say, "Put down that meat cleaver!"
