Since London's segment "Outfit or tablecloth?" was about Bailey's skirt, then London's previous segment "Parachute or Bailey's underpants?" must have been about Bailey's underpants, which (according to London) is huge enough to be used as a parachute.
Kirby's last name is Morris.
This is the second appearance of Kirby since the episode "Showgirls."
Bailey: (sarcastically) Gee, for some reason after becoming the download dork of the day, that thought didn't occur to me.
Bailey: That's what you would say if you were going to "Boo You" me again.
London: But I'm not.
Bailey: And you would say that to throw me off guard. (opens their cabin door)
London: Well, I'm not that smart.
Bailey: But now that I said it, you're smart enough to retain it.
London: (confused) Retain what?
Bailey: Oh, you're good. (exits their cabin with sweater, closes door)
London: Good at what?
(Bailey walks through a doorway)
Woody: Eh, eh, eh, eh, you can't go in there.
Bailey: Why not? This is my cabin.
Woody: Not at the moment. Right now it's a production studio. "Show" business.
Bailey: I meant I would prefer you not mock my wardrobe to the world or lock me out of the room when I need to get... (is cut off by London)
London: An autograph? All right!
Bailey: You just signed my math book.
London: And now it's worth something. (pushes Bailey out of their room)
Bailey: London, don't you realize? You embarassed me in front of Holden, the whole school, and the entire world.
London: Not the entire world. We only have 37 million hits.
(Kirby gives Ms. Tutweiller an apple)
Ms. Tutweiller: Thank you for making the trip, Kirby. Maybe your kindness will rub off on the rest of the class.
Zack: Hey, I brought you a chocolate cupcake just last week!
Ms. Tutweiller: No, you snuck in a chocolate cupcake and I confiscated it.
Zack: You still ate it!
Ms. Tutweiller: Well, it was delicious.
Cody: Thank you. I'm known for my frosting.
Ms. Tutweiller: Nice to see you, Kirby. If you're here to arrest Zack, could you do it during lunch?
Cody: This is a great opportunity for you, Kirby.
Kirby: I know, but the extra cash would bump me into a higher tax bracket, and I don't think my accountant would recommend it.
Cody: I'm your accountant, and I recommend it.
Zack: We're here because, you know, I felt bad about the bungee thing and wanted to make it up to you.
Kirby: You brought me a sandwich?
Zack: Uh, no.
London: Oh, Bailey, do you like this outfit?
London: Are you still mad at me?
London: So, Bailey, how was your hoagie?
Bailey: (muffled) Horrible! And I am very angry about this!
Kirby: Miss Tutweiller, bring on the rest of the test!
Miss Tutweiller: (relaxed; while sitting in vibrating arm chair) In a moment...
Cody: When Kirby comes in, he'll be relaxed by the sound of trickling water.
Zack: What are you trying to do; relax him or make him go potty?
Miss Tutweiller: Poor Kirby; he couldn't get past the first question.
Cody: What was it?
Miss Tutweiller: Put name here.
Zack: I hate that one!
Cody: What about botany? There's no football player named Phil O' Dendron.
Zack: I have a whole different system for that.
Zack: I get a D.
Bailey: Holden? Wow, this invitation really was from you.
Holden: I thought it'd be nice to have dinner together.
Bailey: Are you sure? Last time we ate together, I hocked jalapeno on your shirt.
Holden: I'll risk it.
Cody: Kirby, are you okay?
Kirby: I hate sushi.
London: Aww, so tell us, why does Grammy hate you? (makes a sad face)
Bailey: She doesn't hate me. She loves me. In fact, she calls me her piggly-wiggly and then we'd snort together. (makes snorting sounds)
The German episode title is "Kein (Selbst-) Vertrauen", meaning "No (Self-) Confidence".
Phill Lewis (Mr. Moseby) does not appear in this episode.
London first mentioned her Boo You frown right before her 24-hour Yay Me! broadcast from the previous show The Suite Life of Zack and Cody episode, "Let Us Entertain You".
When Zack tells Cody "If Houdini's brother wouldn't let him do stunts, where would he be?" Zack was talking about Harry Houdini, a magician and escape artist in the 1920s.
