Masculinity is a fragile and serious business. You can find out if you are a real guy in this promotion from an underwear manufacturer. To get the whole flavor of it, answer that you are a model and not a guy and see what kinds of questions you get. Then go back and start again a different route.
What's interesting about this (and the other promotions on that site) is that the way to prove masculinity is by denigrating various feminine stereotypes. That's what I mean by the fragility of masculinity, as it is often defined in the popular culture. If you answer wrong, you fall into the deep and slimy well of womanliness.
