Pete: I didn't realize that everybody here dresses up every year.
Creed: Me neither.

Creed: [covered in blood] It's Halloween. That is really, really good timing.

Dwight K. Schrute: This year I decided to really get into the spirit of Halloween. It may have been the costliest decision I've ever made. My greased up head went into the pumpkin no problem, but ... I can't get it out. I mean, I could try destroying the pumpkin... But as Jim and I discovered, any blow to the pumpkin itself could prove fatal to me. At first I drove myself crazy thinking about the things I should have done differently. I never should have played that joke on Erin. I never should have hollowed out this damn pumpkin in the first place. Then I realized that I was being silly. I mean the pumpkin should rot off of my head in a month or two. Right?

Jim: Angela, it's Halloween. You have to sing "Monster Mash".
Pam: Oh you have to Jim? You literally have to?
Jim: Uh...
Pam: No I'm just, I'm saying, what would happen if they didn't sing it? Would they go to jail? Would they be shot?
Jim: Okay. We'll, just forget it.
Pam: No! No, I'm interested. I mean I think everybody's interested in why they have to sing it.
Jim: Because it is Halloween. So if you're going to sing a concert, it's a good idea to throw that one in.
Pam: Yeah, yeah, no, no. It's a good idea to brush your teeth. But you have to, um, feed your children. Send them to school. You know, all things you can't do if you just keep singing "Monster Mash".

Kevin: It turns out, that Pam really, really hates "Monster Mash". I mean like, never bring that song up in front of her. Even though Jim was making great points, like, in favor of the song, Pam was like, No! Hate it! Stupid!
