In this episode Mr.Larkin is mildly lactose intolerant, but in other episodes he isn't lactose intolerant.
When Mrs.Larkin takes the meatloaf out of the oven, her apron is pink. But a second later, it is yellow.
Mr.Hutchins: Why, Andy, you're amazing. You get 100%. If it weren't for the fact that you're naked!
Andy: Huh? AAHH!
Andy: Ah, the sweet smell of success.
Danny: (coughs) Not only are you exhausted, but you've lost your sense of smell.
Andy: Come on, Danny. You're my right-hand man.
Danny: You mean sidekick.
Andy: Somebody's cranky.
Danny: Cranky? You rushed me out of my nice soft bed, didn't even let me change, and now I'm outside in the middle of the night.
Mrs.Larkin: Andy, if you know what's good for you, you'd better get to the library right now. We'll deal with your punishment after your exams.
Andy: But I'm exhausted. And I don't have to meet Lori for a while. Can't I just sleep a little--
Andy: Fine, I'm going. But I can't believe you're kicking me out when I have exams tomorrow.
Mr.Larkin: We're sending you to the library.
Danny: Train A is leaving the station at 1:45 pm. Train B leaves at 2:30 pm. Both are headed west, and--
Andy: Are they steam engines or those super electric trains?
Danny: (excited) Why? Would it affect how fast they were going?
Andy: Nah, I just wanna picture the right type of train in my head.
Andy: I'm gonna get that B plus, Mr.Hutchins, if it's the last thing I do. (whispers) And it probably will be.
Danny: I've seen an atomic wedgie, a nuclear wedgie, but I've never seen a doomsday wedgie before.
Andy: I figured the world was ready.
