This episode marks the first appearance of Holly, who is to be Toby's replacement at the Scranton branch of Dunder Mifflin.

Andy proposed to Angela in front of everyone at Toby's party, and she accepted. Unfortunately, this was the same moment Jim was going to propose to Pam, and Jim decided to wait rather than follow Andy's proposal.

Ryan is arrested for fraud.

Jan reveals that she's pregnant by a sperm donor.

Pam was accepted into an art training program and will be gone for three months.

Toby: I'd like to introduce you to my replacement.
Michael: Nah.
Toby: Come on.
Michael: No. I think I will pass.
Toby: Michael Scott, this is Holly.
Holly: Hi.
Michael: Hi. Yeah, right. Okay, well, they hired a female Toby. Good for the world. Thank you, God, for creating two of you. Here's how things work here. My job is to make the office fun, your job is to make the office lame. And we have an eternal struggle, you and I. And only one of us can be the winner. Spoiler alert - I'm gonna win.

Dwight: (whispers) Have you been introduced to Kevin?
Holly: No. Which one's Kevin? (indicates Kevin, who's laughing at his desk)
Dwight: He's here on a special work program. He's slow, you know, in his brain.
Holly: Oh, good for you guys.

Kevin: I'm totally gonna bang Holly! She is cute, and helpful, and she really seems into me.

Oscar: Well this is what happened... Uh, Ryan's big project was the website... which wasn't doing so well. So Ryan, to give the impression of sales, recorded them twice - once as office sales, once as website sales. Which is what we refer to in the business as 'misleading the shareholders.' Another good term is 'fraud.' The real crime, I think, was the beard.

Jan: If I was twenty-two, and I had lots of time to have lots of children, then sure, let's let Michael have a shot at one of 'em. But, honestly, I need to make this one count.

Holly: So you missed something really big.
Michael: Yeah?
Holly: Yeah, Andy proposed to one of your accountants.
Michael: Oh, wow.
Holy: I'm not so specific as I can be on my first day, but...
Michael: Well, I can see Andy proposing to Angela. I can also see him proposing to Oscar.

Michael: Thanks to Toby, I have a very strong prejudice against Human Resources. I believe that the department is a breeding ground for monsters. What I failed to consider though, is that not all monsters are bad. Like E.T. Is Holly our extra-terrestrial?

Michael compares Holly to E.T., the friendly alien creature from the 1982 film of the same name.

Michael: (in Yoda voice) Sit on floor and put together chair we will. (laughs uncomfortably) Yo-da. Um...
Holly: (in her Yoda voice) Pass curvy metal piece, you will.

Michael and Holly both speak in character as Yoda, the Jedi master from the Star Wars series of films.

Michael: Kidding. (in dramatic voice) Acting!
Holly: (in dramatic voice) Acting!
Michael: Acting!
Holly: (laughs) Lovitz.

Michael and Holly are imitating the popular Jon Lovitz character, Master Thespian, from the 1980s era Saturday Night Live.

Michael: I have done things like um, 'Beers in Heaven.'
Jim: Classic.
Michael: Or 'Total Eclipse of the Fart.'

Michael has obviously written and performed parodies to the songs "Tears in Heaven" by Eric Clapton, and "Total Eclipse of the Heart" by Bonnie Tyler.

Michael: (to Darryl's band) Do you know, um, 'Goodbye Stranger?' Supertramp?

"Goodbye Stranger" was made famous by Supertramp on their 1979 album, called Breakfast in America.

Jan: ...in fact, it's right next to that little breakfast place that you like in the city where you can draw on the tables.
Michael: IHOP.
Jan: IHOP.

IHOP is an acronym and common name for International House of Pancakes, an American chain of restaurants specializing in pancakes and other breakfast items.

Michael: (to Jim) Hey, what's the group that was from Scranton that made it big? Was that U2?

The band U2 is Irish, of course, but Michael might be referring to musical group Breaking Benjamin, which is from the nearby area of Wilkes-Barre, Pennsylvania.

Jim: (to Michael) Pam and I, we got to know each other right out there. I mean, the first time we joked around was at my desk. And the first meal we ever had was, in the break room, actually. We were at two separate tables and, I remember that. The first time we kissed even, was right outside...

Pam and Jim's first kiss was in the Season Two finale, "Casino Night."

Jim: (leaving a message on Ryan's voice mail) ... I bet you don't think I care enough about this job to actually fight back, but you're wrong, because I do, and I will.

Jim says this because in a previous episode, "Did I Stutter," Ryan told Jim that he knew how little Jim cared about his job at Dunder Mifflin.
