George Sr.: How'd you like to go out for dinner on Friday? Just you and me.
Mary: Why?
George Sr.: 'Cause you're my wife.
Mary: I was your wife last Friday, and we didn't go to dinner.
George Sr.: Mary, I'm asking you on a date.
Mary: Okay.
George Sr.: [chuckles] Is that a yes?
Mary: Sure.
George Sr.: All right, then.
Mary: If you did something stupid, I'm gonna find out.

Sheldon: Regardless, I'm not interested in making any more friends.
Mary: Oh, I don't think that's how you really feel.
Sheldon: It is. From now on, it's a hermit's life for me.
Mary: I bet, when you grow up, you will be surrounded by lots of smart, wonderful friends.
Sheldon: I can't see that happening.

Sheldon: Mom, when should I be expecting my testicles?
Woman: [turns around] What is wrong with him?
Mary: Nothing is wrong with him. Now turn around before I knock your lights out.
Sheldon: Hello.

Mary: Sheldon Lee Cooper, if you don't finish that pork chop, I swear I will chew it up and spit it in your mouth like a mama bird.
Missy: Do it, Mom. Do it.

George Sr.: So he hasn't been in any of your classes?
Ms. Ingram: Mm-mm, not a one.
Ms. MacElroy: Nope.
George Sr.: But I bring him here, I take him home he's got to be somewhere in the building.
Ms. Ingram: Mm, I might've seen him in the library. But at this point, I sometimes think I see him when I'm alone in my house.
Ms. MacElroy: Like that creepy Chucky doll in the movies?
Ms. Ingram: [laughs] Exactly!

[Sheldon is chuckling as he stares at a blank screen]
Missy: What are you doing?
Sheldon: Watching last week's Professor Proton in my mind.

George Sr.: Hey, Hubert. Was Sheldon in class today?
Mr. Givens: Nope. Haven't seen him all week.
George Sr.: Weren't you gonna say anything?
Mr. Givens: I didn't want to jinx it.
