Pastor: In Matthew nine, verse four, Jesus said, "Why would you entertain evil thoughts in your hearts?"
Sheldon: Do you have evil thoughts?
Mary: Ssh.
Sheldon: I just don't think this part applies to me.
Mary: That's fine. Be quiet and listen.
Sheldon: I'm only nine years old. Most evil doesn't start till puberty.

Sheldon: Per the student dress and grooming code, this boy's hair is too long. This boy's wearing sports attire outside a designated area. And this girl's blouse is diaphanous, which means I can see her brassiere.

Sheldon: Hello. Yes, you can help me, Dorothy Fitzpatrick. I'm interested in taking out a second mortgage. I'm nine years old. Why do you ask? That's called age discrimination, Dorothy, but I'm willing to let it slide. I'm glad you find me cute, but I'm deadly serious. I need funds to buy a computer. No, the house isn't in my name. I'm nine. We've established this. I do prepare the taxes for my parents, and if we tighten our belts, we'll have sufficient equity for the loan.

Mary: You understand that some people are going to be intimidated by you, because of how smart you are?
Sheldon: Or maybe they'll recognize my intellect and make me their leader.

Mary: How about we lose the bow-tie?
Sheldon: Why?
Mary: Look around, honey. No of the other kids are wearing one.
Sheldon: Well, perhaps I'll start a fad.

Adult Sheldon: I would go on to draw up such contracts throughout my life With roommates, with my wife. Even with my own children.

Dr. John Sturgis: You know, Sheldon, I'm a notary, if that helps.
Sheldon: Just when I thought you couldn't get cooler.

Adult Sheldon: In that moment, I had an epiphany. I could draw up a contract for any social relationship. It was a helpful way to remove ambiguity in a world that was often hard to understand. Article three Sheldon will not spy on Meemaw's house with binoculars.

Meemaw: I don't want you talking to him about anything having to do with anything about us.
Same with you. And I want you to stop spying on me with those binoculars like you're on some kind of African safari. And you cannot talk to Ira or any of my ex-boyfriends, for that matter.
Dr. John Sturgis: This list is getting long. Maybe we should write it down.

Meemaw: All right, now, listen, if this relationship's gonna have any chance at all, we have to lay down some ground rules.
Sheldon: Great. I love rules.
Dr. John Sturgis: I do, too.
