It's sort of unethical if you think about it in those terms. As a guy, the first thing you want to do is make sure you're not taking advantage. You don't want the girl to feel like you're getting a free feel or something. I try to make a fool of myself in one way or another to lighten the mood and then just go for it, because you don't want to be doing take after take. And I forget every line in the scene. Not just from this movie, from every movie I've done.
