Adult Sheldon: I don't know what could have gotten into her. Probably jet lag.

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.

Pastor Jeff: And now George's loving wife Mary would like to say a few words. Mary.
Mary: Thank you, Pastor Jeff. Um... [clears throat] I met George in high school. Well, I was in high school. He was an older man with a motorcycle. [light laughter] I'd like to tell you he caught my eye, but actually it was the motorcycle. [laughter] [voice breaking] I'm sorry, I can't... do this. I am... so angry. [sighs] George and I had our ups and downs, but we were finally in such a good place, and then he... left. [crying] He left all of us. I- How could you do that? [Meemaw stands up] I am so mad at him. I'm mad at God, I'm mad at myself for not trying harder while he was here. [Meemaw goes up to Mary] This wasn't supposed to happen. [Mary sobs] [Meemaw hugs Mary] [Georgie hugs a crying Missy]

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: Too bad. We are going.
Sheldon: Class is starting tomorrow. I'm not going anywhere.
Mary: Sheldon, do not argue with me. You are going home.
Sheldon: Mom, the people of Germany are obsessed with rules and devoid of humor. I am home.

Mary: Shelly, sit down.
Sheldon: Why?
Mary: Just sit. [sighs] I don't know how else to say this other than just to say it. [exhales] We have to go home.
Sheldon: Oh, no, who did Germany invade now?

Missy: You made fun of her for not having the right insurance?
Dale: It was a joke. The only thing I got wrong was the timing. If I said it two or three years later, everybody's laughing their ass off.
