boxers or briefs and an unanswered question.

My one unanswered question is this.
Why do tighty-whities have a little pocket in the front of them??  I believe they are incredibly nonfunctional.  Is that even a word?

Really, I have been trying to answer this question for many years, and I just can't seem to come to a great conclusion.  It happens to be a question that I have posed to several people, and the general consensus is that if the man doesn't want to pull his underpants down the whole way he can just go through the little peephole pocket thing.

Really?? 

I mean, why wouldn't a guy pull down his underpants all of the way?  I'm not talking to the floor, but, you know, down the way enough to be comfortable.  Wouldn't it take more effort and maneuvering to get your business through the peephole?  I mean, the angle of the pocket is all skewed and stuff.  I guess I can understand it on boxers, because they are looser fitting than briefs, but, who came up with that dumb design anyway??  I mean, why even give them that option in the first place?

I think it could be a good place to carry loose change if you have no other pockets.  Maybe I should write to the manufacturers about it.
