At the beginning of the episode, Meredith isn't wearing her cast, then after the opening credits, she is.
When Jim signs Meredith's cast, he distinctively dots two Is in the last name, so John Krasinski signed it using his real name and not his character's name.
In "The Secret", Jim says he had a crush on Pam when she first started. Pam tells Michael that Jim had a crush on her when he first started. And in this episode, Jim states that Pam lead him to his desk when he first started. Greg Daniels has since said he doesn't know who started first.
As Jim and Michael drive to New York City, one can see in the background the scruffy vegetation of rural to suburban southern California , rather than the forests of northeastern Pennsylvania and northern New Jersey.
Andy: They say you should never mix business with pleasure. Really? Then explain to me how a putt-putt golf course operates.
Dwight: Am I scared of a stupid computer? Please, the computer should be scared of me. I have been Salesman of the Month for 13 out of the last 12 months. You heard me right. I did so well last February, that Corporate gave me two plaques in lieu of a pay raise.
Pam: Dwight mercy killed Angela's cat. It's very complicated. It's caused a lot of unpleasantness between Dwight and Angela, who are both already prone to unpleasantness.
Michael: Well, the website is the brain-child of my brain-child, Ryan. It is my brain-grandchild.
Jim: There's this cube on the screen which bounces around all day. And sometimes, it looks like it's going right in the corner of the screen and at the last minute it hits the wall and bounces away. We are all just dying to see it go right into the corner. Pam claims that she saw it one day when she was alone in the conference room. Okay. I believe she thinks she saw it.
Pam: I saw it. I saw it, and it was amazing. Who said I didn't see it? Did Jim say that I didn't see it? I saw it!
Dwight: (on Andy asking Angela out) I think it's inappropriate to date someone you work with.
Andy: Isn't that part of the fun?
Dwight: No. I think you should date Kelly.
Andy: She works here, too. How is that any different?
Dwight: Uh, she works in the annex. You're also welcome to date Toby.
Dwight: (confessional) I've seen this kid before. He's one of the kids who sneaks onto my farm and steals my hemp.
Delivery Kid: (separate confessional) Yeah, I know that guy. He's that farmer who grows really crappy weed.
The French episode title is "La Fiesta". The Spanish title is "la fiesta de inauguración 2ª parte", meaning "Launch Party, Part 2".
Music: ABBA's "Take a Chance on Me", sung by Andy
This was an expanded, hour-long episode.
Dwight tells the pizza delivery boy that, "because some town in Switzerland says so, you have rights," referring to the Geneva Conventions, which among other things guarantee rights for civilians in battle zones and prisoners of war.
Dwight's battle against the computer in a battle of sales in one day is a reference to legendary African American railroad worker John Henry, who made a bet that he could hammer more rail spikes in one day than a newly invented steam drill.
