Barney: Ohhh. He's gooood. Classic seduction technique.

Marshall: What do you mean?

Barney: First, I buy her, and by her, I mean you, a drink.

Now I'm thguy who gets her what she wants. Then, I pretend to care about whatever idiotic  thing she cares about. For you, that would be the environment. Now I'm the great guty who shares her interests, and before you know it, you're naked in my apartment shouting, "Ohhhhh Barneeeeeeey!" And by you, I mean her.
