Adult Sheldon: Evan upgraded my computer, which made it smarter. There was one problem... the darn thing was smarter than me.
Computer Voicer: Check. [Sheldon groans]

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.

[After Sheldon storms off with his upgraded computer:]
Jim: He gonna be okay?
George: Oh. Tonight, sure. Big picture? [shrugs]
Adult Sheldon: I've got a hot wife and a Nobel Prize. I turned out fine.

Mary: [on the phone] Hi, Pastor Jeff. Can you come over right now? I need you to save someone's soul.
[Cut to Mary opening the front door to Pastor Jeff, who is holding his bible:]
Pastor Jeff: Whose soul needs saving? Is it Sheldon? I've been waiting for this.
Mary: No. We're still praying for him. Come in, we don't have much time.

Georgie: It's for my daughter. Mom baptized her in the kitchen sink, and Mandy's mom did it in a Catholic church.
Sheldon: Sure. Baptists versus Catholics. Much blood was shed over that in the 1500s.
