Zack has serious mental problems with women. The way how he chooses his relations and how he treats women speaks better than words. In first show he wanted to choose the girl simply with best look (indeed, what to do with her brains??) and was disappointed that his roommate was Amy, even not giving the chance to know her better, he complains into her face about it (what a man u are after it?). When Amy is "falling on her knees" in front of him in public, swallowing all abasements from him and keeps hanging over him, he feels pleased, now he is satisfied with her, cuz his buddies tell - hey u are MAN, this girl is running around and singing hymns to you. Now he feels as a MAN with such woman, that is why he decides to keep her. BUT his real tastes are far away from Amy.It is proved in PH 2, where without doubts he chooses brainless blond white teeth barbie with massive boobs, who is sleeping around and get drunk. Her blond hair, good teeth and boobs are the best choice for guy who dreams to look "macho" for his buddies. Exactly what Zack wanted from beginning (remember - he tells Amy that she is fat and not attractive). So he chooses the girl who slept for the first night with half of hotel and even tried to seduce girls, and who for all show didnt say any clever word from her sexy mouth. On final intervew she was asked if she slept her way to top? LOL GOOOG choice, Zack!
After show she dumped him. Finally now he is married..it is asian girl and they live in Hawai. I would be very very surprised if he dated a lawyer or politican woman. Zack is always mix of his weakness as man and his biggest wish to show off to everybody thta he is a man. I can only suppose that he grew up by strong affection of dominating mother, because all his behavior is behavior of a man who cannot have strong selfconfident women in his life anymore. To be honest I cant understand how anyone can admire such type of person?
