Reality TV

Are people on reality TV shows that dumb? I was watching Average Joe on NBC I think and they had a "boys night out" at a local bar. The night starts out normal then they bring in some hot models to flirt with the guys and a bunch of em went for it. What's up with that?!? Now think of it your on a TV show and suddenly some hot chicks hit on you uhhh lets think about this for a sec. Your on a freaking TV show about dating most people, would think twice I would gather. Maybe that's one of the parameters they look for when choosing contenders. Just makes me think on how real reality TV is? The chicks all crying cuz the good looking guys that she really liked was one of the guys went for it. Made me laugh it was funny.
