Jack: You're always in such great shape.
Winthrop: Same weight as when I wrestled at Yale, Jack.
Jack: Winthrop here wrestled at Yale.
Devon: With other dudes, or...?
Devon: Here, why don't you take some of my steak? I could never eat this much meat.
Jack: That's not what I hear.
Jack: Banks, what are you doing in town? You drawn to the phallic nature of our skyline?
Angie: (to Tracy) No more jewelry with my name misspelled. No more sexually explicit sky writing. And no more white boys throwing up in my damn foyer!
Frank: Holy crap! Did your tooth just fall out?
Liz: Oh, that's not great, huh?
Kenneth: I like your top. I'm a real good sex person. I do it all the different ways.
Angie: Uh-huh. Well, I don't have a husband any more, so... you can come over anytime.
Kenneth: Oh, I will. I'll come over at night.
Jenna: I'm on a crash diet to get back to my old weight by Friday.
Liz: Well, what diet is going to do that?
Jenna: Oh, it's the Japanese porn star diet. I only eat paper, but I can eat all the paper I want, so...
Jenna: (to Liz) It's kind of hard to take life advice from a single woman who's using her treadmill as a hanger for a wedding dress.

Dr. Spaceman: Did you know, scientifically speaking, that humans want food, but don't need it?

Devon: Are you familiar with the Church of Practicology?
Jack: You mean the cult that was invented by Stan Lee?

Liz: (to Jenna) Don't let people make you crazy about this. You are just as beautiful and talented as you ever were.
Jack: No. No, no, no. You are fat. Go see Dr. Spaceman right now and get this taken care of.
Liz: How come men can be heavy and be respected, like James Gandolfini or Fat Albert? It's a double standard, and America needs to get over its body image madness.
Jack: Oh, come on. What are we, back in college, freshman year? Let's go to the common room and talk about apartheid.
Liz: Oh, okay. Yeah. I'm sorry I care about making the world a better place.
Jack: You should be. It's a complete waste of time.
Dr. Leo Spaceman: Now Jenna, medically speaking, for your height your weight puts you in what we call the "disgusting range". Fortunately, there are solutions. For example, crystal meth has been shown to be very effective. How important is tooth retention to you?
Kenneth: Dotcom I have an idea ...
Dotcom: Well I don't know but it's worth a shot.
Kenneth: Are you even listening to me?!
