2x14 Advanced Dungeons and Dragons DVD Commentary

Dan Harmon: What’s amazing about it, not to blow my own show or anything, but what I love about this, is that our character, our douchiest character, who’s our protagonist, our most hair gelled, most buff, most stylish character, who is the most wise guy on a ship of fools, the closest to David Spade that we have on our show, starts from the base of caring about human life and not wanting blood on his hands. Even the character who is defined by his solipsism has that much compassion. Like, knows that you’re supposed to save human lives. You’re not supposed to let people kill themselves for being fat. Then we find out that he’s riddled with flaws. That [Jeff], in fact, is the reason that [he] alone cannot solve this problem and stuff. And that’s the twist. But we start the episode not with people going, “Oh, he’s fat. This is Dungeons and Dragons. I don’t like it.” And then finding out, “This isn’t so bad after all.” It just starts with, “Okay, let’s save this guy’s life, right? Because that’s what you do.”  

2x11 Abed’s Uncontrollable Christmas DVD Commentary

Dan Harmon: Every character shares some aspect — is based on an aspect of the writer, eventually. … I’ve been told several times by therapists … my childhood … kind of fried the circuitry in my heart which is why I have trouble with relationships. That’s why [Britta is] a robot. 

2x16 Intermediate Documentary Filmmaking DVD Commentary

Dan Harmon: This is a great exchange. Watch Britta, whose circuitry is unwired. 
Megan Ganz: Her face here.
Dan Harmon: That’s her reacting inappropriately, as Annie points out. … something scarred her, rewired her circuit board and she doesn’t react appropriately. So that’s why she’s the robot in the Christmas episode. She has these behaviours that don’t — there’s overlap there with her and Abed. 

2x22 Applied Anthropology and Culinary Arts DVD Commentary aka, The One in Which Donald and Gillian Have Sex (and crash in on the commentary multiple times)

Donald Glover: Do you guys have any cement?
Yvette Nicole Brown: Donald.
Ken Jeong: We don’t have any cement.
Donald Glover: [Gillian] wants cement. 
Ken Jeong: Why would we have cement here? What is that even used for? Cement? 
Yvette Nicole Brown: This is a bit that he does on set.

Gillian Jacobs: All I wanted was some cement in my mouth. I don’t understand why that’s so hard. Surely, you have some cement in this sound booth. Donald and I are quietly having sex. 
Jim Rash: What’s the cement for?
Gillian Jacobs: I like it in my mouth. I don’t need to explain to you why I like it but I need it. 
Yvette Nicole Brown: Gillian, I am so upset. It’s so inappropriate and unprofessional. It’s bad enough we have to watch it, but for you to come in and describe it. I’m really bothered. 

Ken Jeong: Donald Glover coming in.
Donald Glover: [Gillian] wasn’t really upset, that’s something she has to do after all the sex we have. She has to get angry at a group of friends. Don’t be mad, don’t be upset. That’s something she does. 
Ken Jeong: Donald, the fans want to know more about Gillian Jacobs and her sex habits.
Donald Glover: Do you have anything sharp?
Yvette Nicole Brown: Donald.
Donald Glover: We can’t finish unless I hurt myself very bad. 
Gillian Jacobs: I just like a little blood after the cement.
Yvette Nicole Brown: Not the time! Not the time! 
Donald Glover: I just want to let everyone know that I came. 

Yvette Nicole Brown: I am so sorry everybody.
Ken Jeong: Give it up for Donald and Gillian having sex. Good job.

Yvette Nicole Brown: What did we miss in all that? Did we miss any points we wanted to make? 
Ken Jeong: I think we covered everything very well.
Jim Rash: I think people learned more in this commentary than ever before.
