These potential gigolo farms are teaching men how NOT to be themselves and do the exact opposite of what they would do in the situation. It reminded me of those Extreme Makover shows, but slightly perverted, the "overhaul your personality" edition. And really, at some point, a girl doesn't want bull-sh** mind-rape games, because it's a waste of time and energy.
Even if "pick-up line" university teaches them how to approach women, it doesn't teach them how to approach other people in non-romantic situations, which if they are painfully shy, they'll still have a problem with. And then what? After they get the girl then how do they know how to conduct that relationship? Does the girl respect Mr. Wonderful after she realizes he just knew some pick up conversation? It smacks of corny.
