Jim announces to the office that he and Pam are engaged.

Cooper's Seafood House, where Michael takes Holly for lunch, does indeed have a restaurant in Scranton.

Pam does not appear in this episode, though her voice is heard while on the phone with Jim.

Andy: I'll drop an ethics bomb on you. Would you steal bread to feed your family? Boom!!!
Oscar: Exactly, Andy.
Andy: Yeah, I took Intro to Philosophy. Twice. No big deal.
Dwight: It's a trick question. The bread is poisoned. Also, it's not your real family. You've been cuckolded by a stronger, smarter male.

Angela: I once reported Oscar to the INS. Turns out he's clean, but I'm glad I did it.

Meredith: I'll go. Have you guys ever met Bruce Meyers, the Scranton rep for Hammermill?
Michael: Bruuuuuuce.
Meredith: Well for the past six years I have been sleeping with him in exchange for discounts on our supplies and Outback Steakhouse gift certificates.
Jim: Jackpot.

Jim: (about Dwight) He has not stopped working for a second. At 12:45 he sneezed while keeping his eyes open, which I always thought was impossible. At 1:32 he peed, and I know that because he did it in an open soda bottle under the desk while filling out expense reports. And on the flip side, I have been so busy watching him that I haven't even started work. It's exhausting being this vigilant. I'll probably have to go home early today.

Holly: (about Meredith) I'm saying that her behavior is unethical, and a little icky, and I don't think I want to work in an environment where that sort of conduct is tolerated.
Michael: Well, you have to tolerate a lot when you are part of a family.
Holly: It's not a family. It's a workplace.

Ryan: Anyone see Survivor season six? Anyone know Joanna on that show? In New York City, I hooked up with a girl who looked exactly like that. Indistinguishable. So...

Ryan is talking about the hit reality show Survivor which airs on CBS, and Season Six contestant, Joanna Ward.

Michael: When I discovered YouTube I didn't work for five days. I did nothing. I viewed Cookie Monster sings 'Chocolate Rain' about a thousand times.

Michael refers to the lovable Muppet, Cookie Monster from the children's show Sesame Street. The video Michael talks about is a real video on YouTube.

Michael: Wow, terminator, terminator.
Holly: I'm from da future.

Michael and Holly both imitate the voice of Arnold Schwarzenegger in the 1984 film, The Terminator.

Jim: (to Andy) By any chance, did you see Battlestar Galactica last night?

Jim makes a reference to Battlestar Galactica, the popular science fiction television show that airs on the SciFi network.

Jim: (to Andy) I mean I like all the crazy monsters and stuff. You know, like Klingons and Wookies... and all that but...

Jim intentionally mixes up names of creatures from various films and shows to anger Dwight. Klingons are originally from the series Star Trek, and Wookies are from the Star Wars films.

Jim: (to Andy) Story's kinda bland. It's about this guy named Dumbledore Calrissian who needs to return the ring back to Mordor.

Jim blends the character Dumbledore from the Harry Potter series of books with Lando Calrissian, from Star Wars, then tosses in the location of Mordor which is from the Lord of the Rings series.

Holly: Today we're going to have a business ethics seminar because recently, without mentioning any names, there has been some misconduct at corporate and we have a very strict ethics policy, and that employee has been fired.
Kevin: Oh come on! He's right there.

Kevin makes a reference to Ryan being fired for fraud, which occurred in the Season Four episode "Goodbye Toby."

Kevin: (speaking to Jim, but referring to Ryan) Oh check it out - Hired Guy.

Kevin alters the nickname of "Fire Guy," which Ryan earned in the Season Two episode "The Fire" for burning something in the microwave, to "Hired Guy," which refers to the fact that Michael re-hired Ryan as a temp receptionist in the previous episode, "Weight Loss."

Jim: Well I guess I can assume that was personal.
Dwight: (the camera focuses on Angela, who is buttoning up her blouse) Fine.
Jim: So maybe you're not completely ethical after all.
Dwight: Yes, maybe I'm not. (Dwight smiles knowingly at the camera)

Dwight knows he's not being ethical, as he and Angela are still carrying on their affair behind Andy's back. They began cheating right after Andy proposed to Angela, during the Season Four finale, "Goodbye Toby."
