Aside from the pure entertainment value, I'm glad the guys on the show talk so frankly about their prowling and hook-ups. I think there are girls out there who can really benefit from seeing how some guys view them—as meaningless hook-ups they can brag about later. We all get warned along the way, but watching it unfold on TV helps illustrate the point pretty clearly.
