Phyllis: This is the first Christmas party I am throwing as head of the party planning committee. The theme is 'Nights in Morocco.' This isn't your grandmother's Christmas party. Unless of course she's from Morocco, in which case it's very accurate.

Angela: I am not going to judge Phyllis for desecrating Christmas. There is one person who will though, and Phyllis just stuffed him into a drawer.

Michael: That is vodka and I mixed it with orange juice. I call it an orange-vod-juice... ka.
Jim: Wow, that is delicious.
Michael: Yeah.
Jim: Can't believe no one's thought of that.
Michael: I know!

Angela: Really Andy? It's Christmas and you're singing about nudity, and France.

Meredith: I don't mind telling you that I have an addiction. I do. To porn.
Michael: All right, no, no, no. No. That is the image, I think we can all agree is very disgusting. But you know what, Meredith, you lit your hair on fire today. What about tomorrow? What is going to happen when you come into work and you're dead?
Dwight: I stab her in the brain with a wooden stick.

Michael: As it turns out you can't just check someone into rehab against their will. They have to do it voluntarily. They have to hit rock bottom. So I think I know what I need to do at this point, I need to find ways to push Meredith to the bottom. Um... I think I can do it. I did it with Jan.

Michael: (to Meredith) Was John Belushi fine? Was Bob Hope fine?

Michael tries to convince Meredith to quit drinking by bringing up the drug-related death of comedian/actor, John Belushi. Clearly, Michael also seems to think comedian Bob Hope died of a drug overdose too, though in reality he died of natural causes.

Phyllis: (to everyone nearby) Angela's having sex with Dwight. I caught them doing it after Toby's going away party.

Phyllis first learned that Dwight and Angela were having an affair during Toby's going away party in the episode, 4x14 "Goodbye Toby."
