[flashback to Marshall in Jefferson Coatsworth's office:]
Jefferson: Marshall, why don't you want to work at Nicholson, Hewitt and West?
Marshall: Right, um, okay, Jeff, I've actually given this a lot of thought...
Jeff: I'm sorry. Stop. I can't do this with a straight face. You don't want to work here. You're only here 'cause your dad went to high school with Joe Hewitt. Fact is, you just got a sweet job at the NRDC. And it's awesome. Man, I could have gone the non-profit route. I didn't. And it eats me up inside every day. I hate myself. I hate myself.
[back to the gang at MacLaren's:]
Barney: Oh, he is good. Classic seduction technique.
Marshall: What do you mean?
Barney: Oh, I use it all the time. First I buy her, and by her I mean youm a drink. Now, I'm the guy 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. [puzzled expression] Now, I'm the great guy who shares her interests. And before you know it, you're naked in my apartment, shouting "Oh, oh, Barney!" And by you, I mean her.
Marshall: He is not trying to seduce me. He didn't even offer me the job.
Barney: That comes later. At dinner. He did invite you to dinner, didn't he?
