Sheldon: Hi, Mom.
Mary: What did you do?!
Sheldon: Good news. I found out what part was making that noise.
Mary: You have to put this back together!
Missy: Now we're getting to the bad news.
Mary: What made you think you could fix this?
Sheldon: I'm smart and I had a book.
Mary: Do you still think you're smart?
Sheldon: Yes.
Missy: I told him not to do it. He wouldn't listen.

Mary: Missy, if you want a minute with Dad before they close the casket, now's the time. [Missy looks unsure] It's okay if you don't.
Mary: I have to. [Missy stands up and walks up to her father's casket]
[flashback:]
George: Here, let me help you with that. Okay.
Missy: [eats] Holy moly.
George: It's good, huh?
Missy: Unbelievable.
George: I'll leave you to it.
Missy: No, sit with me.
George: Okay.
[present:]
Missy: [crying] Thank you for that. Thank you for everything. [sniffles] I love you.

Sheldon: Is Mom okay?
George: How the heck should I know?
Missy: She left. You can say "hell."

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.

Adult Sheldon: Ignoring things that irritate me isn't my strong suit. Obsessively fixating on them, now that's what gets me out of bed in the morning.

Adult Sheldon: My father's wisdom touched me deeply. Which is why, to this day, no matter what I'm going through, I am never irritating or abusive to any of my friends or loved ones. Ask them. They'll tell you.

Billy Sparks: Hey, Sheldon.
Sheldon: Hello, Billy.
Billy Sparks: Are you our new paperboy?
Sheldon: Yes, I'm joining the work-a-day world.
Billy Sparks: I work, too! I take care of our chickens.
Sheldon: Don't get the wrong idea. When I grow up, I plan on being a theoretical physicist.
Billy Sparks: Cool. I'm sticking with chickens.
Sheldon: All righty then. Have a nice day.
Billy Sparks: You, too. [looking at the newspaper] Oh, cool, it's Monday.
