After Michael mistakes the company's tech support employee for a terrorist, he informs Michael that he can monitor his employee's e-mails which causes Jim to worry that Michael will discover the party he is throwing that night, to which Michael is not invited. Inevitably, Michael notices and tries to get Jim to admit that he's having a party, while Jim acts nonchalantly as if nothing is happening. Pam notices some things that lead her to suspect that Dwight and Angela are dating. However she discreetly abandons her suspicions when she realizes that suspicions could just as easily be raised about her and Jim. Jim and Pam bond when she sees Jim's room for the first time and looks through his high school year book. After ruining an improv class, Michael decides to crash Jim's party, much to the staff's dismay (and Dwight's cluelessness). The documentary crew catches Angela and Dwight making out in Jim's backyard.

• John Krasinski and Jenna Fischer had a major laughing fit during the lunchroom scene with Michael. Jenna stated she was amazed they were able to cut the scene together.
• When in the lunchroom Michael mentions that he misses the parties he used to go to at college, even though in an earlier episode, "The Fire", he admitted to Ryan that he never went to college. However the story may have just been made up in an attempt to get invited to Jim's Party, especially since Michael makes a point that the professors (and by analogy, the boss) were invited.
• Fischer's favorite moment of this episode is when Phyllis sings Karaoke. Although her character sings Whitesnake's "Here I Go Again," the actress Phyllis had never actually heard of the band and practiced for days beforehand before the scene was filmed. Fischer and Angela Kinsey stated everyone on the set was laughing.
• Kevin calls Ryan the "Fire Guy", referring to the episode "The Fire".
• At the start of the tour, Jim reveals to Ryan that he hasn't talked with Katy for some time, foreshadowing their eventual break-up in "Booze Cruise".
• Angela Kinsey improvised the line (outside with Dwight at the party), "I think that's all right. I mean, Jesus drank wine." She was apparently very surprised it made it in the final cut of the episode.
• Dwight and Angela are actually making out in a small dollhouse in Jim's backyard. There was a scene that was cut that explained that it belonged to the people Jim rents the house from.
• Kate Flannery, playing Meredith drunk at Jim's party, jokingly pretended to pull her top up at the camera. Although the scene wasn't used, the writers wrote the topless gag multiple times in later episodes. Flannery states, "I think I did it to myself, unfortunately. My parents are real thrilled about that."
• There is a reference to the George Orwell book Nineteen Eighty-Four. When Oscar asks about the "Big Brother" implications of e-mail surveillance, Michael replies that "I love my big brother".
• With this episode, the US version of The Office officially surpassed the British counterpart in total number of episodes including two Christmas specials.
• In the Evite for Jim's BBQ, the time and date of the party was November 5 at 8pm. The address was 2147 West Silverlake Drive.

Kevin: Michael, should I call the (Michael gestures maniacally to be quiet) … what?

IT Guy: What’s your password, Michael?
Michael: Um …
IT Guy (looking at post-it on Michael’s computer): Oh, 1-2-3-4.
Michael: Yes.

Dwight: You could get a brain aneurism.
Michael: I’m not going to get a brain aneurism.
Dwight: Or hit by a car. Or a bus. Or a train. Or get poisoned. Fall down a well. Step on a mine. Choke.

Michael: The problem is that when people hear the term “Big Brother,” they immediately think it’s scary or bad. But I don’t. I think, “Wow, I love my Big Brother.”

Kevin: I gotta erase a lot of stuff. A LOT … OF STUFF.

Pam: It’s like squishing a spider under a book. It’s gonna be really gross, but I have to look and make sure that it’s really dead.

Pam: Hey, Dwight? Um, my friend is kind of into these two girls that he works with.
Dwight: Nice.
Pam: One is tall and brunette. And the other one is short and blond and perky and kind of judgmental. Who do you think he should choose?
Dwight: Does he have access to their medical records?

Dwight: There are a huge number of yeast infections in this county. Probably because we’re down river from that old bread factory.

Michael: Wonder where my Evite-tation is.

Michael: But maybe I need to be even approachabler.

Michael: Hangin’ with my crew. Crew that I am one of. Hanging with my Cup of Noodles. This is a meal in a cup, right here. Hot, tasty. Reminds me of college. Lived on this stuff. Brain food.

Jim: It’s true. I’m having a party. I’ve got three cases of imported beer, karaoke machine, and … I didn’t invite Michael. So … three ingredients for a great party. And it’s nothing personal, I just think that if he were there, people wouldn’t be able to relax and you know, have fun. And my roommate wants to meet everybody. Because … I’m pretty sure he thinks I’m making Dwight up. He is very real.

Jim: … my roommate wants to meet everybody. Because I’m pretty sure he thinks I’m making Dwight up. He is very real.

Jim: So Dwight thinks that tonight is a surprise party for Michael.
Pam: Really? That’s great. Maybe we can get him to hide and wait somewhere.

Michael: What?
Jim: I think Stanley just coughed.

Michael: Hey, Pam. Do you need me to walk you to your vehicular transport?
Pam: No thanks.

Dwight: I have to go to practice. Soccer practice.
Michael: I didn’t know you played soccer, Dwight.
Dwight: Clarinet.
Michael: You too, Dwight?

Dwight: Jim, do you really think this is a good idea? Huh? A “hide a key” rock?
Mark: Hey, you must be Dwight.

Mark: Hey, I love the Birkenstocks.

Michael: What is the most exciting thing that can happen on TV or in movies or in real life? Somebody has a gun. That’s why I always start with a gun, because you can’t top it. You, you just can’t.

Michael: Detective Michael Scarn. I’m with the FBI!

Improv instructor: Michael, I want you to give me all the guns you have.

Jim: Um, you know what? Let’s just leave that image out of it. Because this is a happy place. Happy thoughts, Pam. Happy thoughts.

Pam: You were so dorky!

Jim: Chicken, hot dog, burger.
Angela: I’m a vegetarian.
Jim: There’s soda inside.

Angela: Um, I think it’s alright. I mean, Jesus drank wine.

Kevin (slapping Ryan’s hand away from the grill): Not so fast, Fire Guy.

Phyllis: Here I go again on my own. Going down the only road I’ve ever known.

Pam: Just because two people are hanging out, it doesn’t mean that they’re together … you know? Like people can just be friends. And I think that it was really unfair of us to assume that there was anything else going on.

Michael: Who opened the morgue for this thing?

Michael: He is a good guy. Not a terrorist.

Michael and Jim (singing): Islands in the stream, that is what we are …
