Mary: Do you even think about how your actions affect other people?
Brenda Sparks: Love it. Keep it coming.
Mary: You couldn't hang on to your crappy husband, so you tried to move in on my crappy husband.
Brenda Sparks: Good, good. That hurt, but good.

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.

Meemaw: You know who claps three times? Yankees.

Meemaw: Otherwise, we might as well just live in Oklahoma. Blech.

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.

Sheldon: I know a way for you to watch whatever you want.
Missy: How?
Sheldon: Your imagination.
Missy: That's stupid.
Sheldon: Did you know there's a German folk song about it?
Missy: Don't.
Sheldon: [sings] ♪ My thoughts will not cater ♪ ♪ To duke or dictator ♪ ♪ No man can deny ♪ ♪ Die gedanken sind frei. ♪ [talks] Where are you going?
Missy: Mom said no music.
Sheldon: [hums melody]
