I remember seeing on Discovery channel a while back an English doco about the human body. Interestingly, for here, quite a few of the nude males were reasonably well hung. Well, not well hung really, but definitely at the higher side of average.
Yes, I remember that series well. It was shown in Canada 4-5 years ago.
I believe it is one of the best series on the human body.

At 3:09, you can see the huge bulge in khaki pants.
