Mandy: I can't believe you lied to me.
George Jr.: Only 'cause I like you.
Mandy: Get out.
George Jr.: Come on, I'm the same guy I was five minutes ago.
Mandy: Yeah, a liar.
George Jr.: You lied to me about your age.
Mandy: Yeah, and then I felt really bad about it, and I told you the truth.
George Jr.: 'Cause you're more mature than me.
Mandy: Go.
George Jr.: Can I at least put on my shoes?
Mandy: No.

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.

Adult Sheldon: I may have promised Paige I wouldn't tell my mother. Thankfully, Missy didn't. I don't know what lip gloss flavor says "mature," but that would be my sister.
Mary: Paige?
Missy: Where is she?
Sheldon: There's a note. "Sheldon, thank you for letting me stay here, but I have to go. I'm happy you're doing well. I need to find that for myself somewhere. I hope I can. Your friend, Paige."
Adult Sheldon: After a few frantic nights, Paige showed up at her mom's. They had a lot to figure out. Being a parent isn't easy. I know I made life difficult for my family. And my own kids do the same to me. Just yesterday, I had to take my son Leonard to the skate park, like a regular park isn't bad enough. It's safe to say, having children is challenging.

Sheldon: I can relate. A young lady brought chaos into my life as well today.
Missy: What happened?
Sheldon: Paige was visiting the university and got mad that I have college friends and she doesn't.
George Sr.: You're drunk, Sheldon has friends. This a crazy-ass dinner.

Paige: Your neighbors let you hang out with them?
Sheldon: I'm basically the social glue of our floor.
