Dwight: So you got the fax. So why didn't you add it to the resume? What do you mean? Of course martial arts training is relevant. Oh excuse me, I know about a billion Asians that would beg to differ. Uh, yeah, I get a little frustrated when I'm dealing with incompetence. Well, you know what? You can go to hell and I will see you there. Burning. Fine. Oh, wait, so you'll let me know when you've made a decision?

Jim: Dwight is special. But I don't believe that his talents are being used in this office. So Pam and I have put his resume on Monster.com, Google, Craig's List. We're really interested most in jobs that take Dwight out of state. Preferably Alaska... or India.

Michael: Oh, look at you. Showin' your colors. I bet you wish you wore a dress everyday.
Oscar: What are you implying?

Angela: Those aren't chips and dip.
Pam: No, I made brownies.
Angela: (Sighs)
Pam: What?
Angela: I'm just trying to figure out why you're trying to sabotage things.
Pam: (Bewildered) I made brownies.
Angela: And I made cookies. Same category.

Michael: Devon wait, please, look, in addition to severance and everything, I want to give you, this gift certificate from Chili's, from me. Okay? No hard feelings.

The janitor vacuums up the cobwebs, but you'd think he would leave them, realizing they are part of the other Halloween decorations that are hung around the office.

Jim pretends to be Michael on the phone, yet Michael is sitting just ten feet away. Most likely he would have been heard.

When Pam wants to see what is happening to Jim while he's in Michael's office, she finds the first set of blinds closed, but she never looks through the second set.

Michael: Interesting take on Dorothy. I love it. Hey, you know what would even be better? Soccer ball and cleats.
Kelly: Why is that?
Michael: Bend It Like Beckham.

Michael is implying that Kelly should pretend to be the girl from the 2003 film, Bend It Like Beckham, about an Indian girl who plays soccer.

Stanley: You're fired! Get your fingers off my phone.

Stanley makes a quick reference to another NBC show, The Apprentice.

Phyllis: What are you? A monk?
Dwight: I'm a Sith lord.

Dwight's costume is a reference to the Star Wars series of films, in which the Siths are cult of priest-warriors that follow the dark side of the Force.
