Mary: Hey, Missy, you awake? [knocks] It's Pancake Sunday.
Missy: [opens door] What's that?
Mary: Well, it's a fun new thing I thought we could... Where are you going?
Missy: I told you. Six Flags with Jamie's family.
Mary: Oh. Well, I could make you pancakes first.
Missy: Pancakes and roller coasters? Do you want me to barf?
Mary: Well, no.

Sheldon: While Dad's gone, I'm the man of the house, and the man of the house has to enforce the rules.
Missy: The man of the house is about to get his teeth knocked out.
Sheldon: Puberty's made you mean.
Missy: I need to know what happened on my show.
Sheldon: And you'll find out when your privileges are restored.
Missy: I can't wait that long, each episode builds on the last. Imagine a Star Trek that ends with "to be continued," and you don't get to continue.
Sheldon: That would never happen, because I follow the rules.
Missy: You are this close to a purple nurple.
Sheldon: [covers nipples] You leave my nurples alone.

Missy: One question.
George: Yes?
Missy: What's 0600?

Missy: I'm totally into old movies. You know, Breakfast Club, Goonies, Pretty in Pink.

Sheldon: Mom.
Mary: [wakes up] What is it, Sheldon?
Sheldon: I know you had some questions about Star Trek, so I've compiled a detailed guide outlining all the shows, characters, and how they fit in a timeline.
Mary: Can we do this later? I've got a headache.
Sheldon: Unfortunately not. If we don't do it now, you'll be completely lost when we watch The Animated Series this afternoon.
Mary: Just 20 more minutes.
Sheldon: Mom, this is almost a hundred pages. We have to get started. In the 23rd century, alien races from around the galaxy have come together to form the United Federation of Planets, which is... open your eyes... Headquartered in San Francisco.

Sheldon: Since when is it Pancake Sunday?
Mary: Since today.
Sheldon: No, it's not. It's Kellogg's Bran Buds Sunday, like it's been for the past three years.
Mary: Well, I thought it would be fun. I'll- I'll make you any kind of pancake you want.
Sheldon: On Bran Buds Sunday?
Mary: Fine. I'll put Bran Buds in the pancakes.
Sheldon: That could work.
[cut to Mary watching Sheldon eat at the kitchen table:]
Sheldon: [mouth full] It doesn't work. [spits out food]

Mary: Oh. I didn't realize my mom had company.
Dale: Yeah. Uh, do I have to pretend I didn't spend the night here, or...? I don't know how this works.
Mary: It's fine, uh... you could've said nothing, but now I know.
Dale: Yeah. What's with the pancakes?
Mary: Oh, I made extra, so I was just bringing 'em by.
Meemaw: [o.s.] Who's at the door?
Dale: It's Mary! She knows I slept with you. Come on in.
