The Gerard Butler Paradox: Why do women like Gerard Butler? Gerard Butler is not conventionally attractive. Gerard Butler is not talented. Gerard Butler is not actually even that funny. However, Gerard Butler is MANLY. Yes, with capital letters. He is muscular in the way that men who work out but also drink a lot of beer are muscular. He is dirty (see Brad Pitt Rule). He is offensive (think frat boy), he is promiscuous and dickish with a "heart of gold" (think Barney Stinson), and he's just MANLY.
