Missy: This cake is amazing.
Mary: To look at, sure. I prefer cakes for eating.
Missy: What's your problem?
Mary: What's your problem?

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.

Mandy: [sighs] Hey. I didn't know you were here.
George Jr.: Just checking out the loot. This is amazing. Why don't all bras do this?
Mandy: Take that off.
George Jr.: Well, that's what's great: you don't have to. Look at this.
Mandy: The father of my child.
George Jr.: Ooh, nipple cream. Maybe I should've went to this party. Sounds fun.

Dr. Linkletter: It's open.
Sheldon: Hello. [Dr. Linkletter groans] I was wondering if I could have access to the lab on Sunday.
Dr. Linkletter: I'm not here on Sunday.
Sheldon: Where will you be?
Dr. Linkletter: If I tell you that, you might go there.
Sheldon: Well, I told you where I'll be: the lab.

Mary: All right, please, uh, say goodbye to your husband.
Audrey: Well, you can tell him yourself. He's hiding behind that stack of tires.
[Jim emerges from behind the tires and gives Mary a little wave]
Mary: Bye.
