George: Damn it. I've had enough of this. Sheldon, get up.
Sheldon: What's the point?
George: We're going to Houston.
Sheldon: Really?
George: Yeah. You and me are gonna give those space monkeys a little talkin' to.
Adult Sheldon: I often found my father to be a strange and puzzling man, but at that moment, I never loved him more.

Adult Sheldon: I didn't realize until years later that my father was only asking questions about lightning and thunder to cheer me up. In fact, he would often pretend to be dumb just to make me feel better.

Adult Sheldon: My father didn't always get the credit he deserved. The advice he gave me actually worked out pretty well. Of course, I never told him.
George: Talked to Billy.
Missy: Why would you do that?
George: No, it was good.
Missy: Stay out of my life.
Adult Sheldon: He may not have been the world's greatest dad. But maybe we weren't the world's greatest kids.

Pastor Jeff: Before our final prayer, would anyone else like to say a few words?
Mary: Missy? [Missy shakes her head] Shelly?
[Sheldon stands up and walks up to the microphone]
Sheldon: I've been thinking a lot about the last moments I had with my dad. It was morning, and he was leaving for work. He said, "See y'all later." And I said nothing. I regret that. I could have said "bye" or asked him for a ride. Or told him that I loved him. But I didn't. I barely noticed he left. So many times that I didn't notice my father. I hope he knew how much I loved him.
Adult Sheldon: I wish I could tell you I said all those things. But I didn't.
Mary: Shelly? [Sheldon shakes his head] [Mary shakes her head to Pastor Jeff]
Pastor Jeff: Let's bow our heads in prayer.
All: Our Father, who is in heaven, hallowed be Your name...
Adult Sheldon: For a long time, I focused on my father's shortcomings. Now that I'm his age and have kids of my own, I realize he was just a person doing the best he could, and he did a lot. I didn't say it at his funeral, but I can say it now. I loved my father. I will miss him forever.

Meemaw: So I saw a lawyer today.
Mary: Why?
Meemaw: I'm putting together my last will and testament.
George: We're gonna miss ya.
Mary: George.
Meemaw: Don't worry. I ain't leaving him squat.

Mary: Sheldon, who are you talking to?
Sheldon: Dorothy Fitzpatrick.
Mary: Who's Dorothy Fitzpatrick? Is she a new buddy from school?
Sheldon: She's the loan officer at The First National Bank of Medford.
Mary: Why are you talking to her?
Sheldon: Mom, can this wait? I'm trying to negotiate favorable terms. Hello, Dorothy? [Mary hangs up]

Adult Sheldon: People often wonder why I chose to pursue a career in theoretical physics. I usually respond by saying I wanted to unravel the inner workings of the universe. But the real answer was I wanted to prove this nincompoop wrong.
