Adult Sheldon: Classical physics can predict a lot about the world. For example, it can tell us what happens when one pool ball knocks into another. But when multiple balls careen in different directions, we've entered the wild and woolly world of nonlinear dynamics. And you don't need me to tell you that it's impossible to predict what will happen next. Actually, based on the state of our educational system, you probably do. Now imagine those are people. Even a brilliant young ball who graduated high school at 11 can be caught in the maelstrom. Aah! Our first collision was set in motion when Pastor Jeff and Robin had their baby.

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.

Mary: You are right. You have been here longer than me. I don't see why we can't work together.
Peg: That'd be nice.
Mary: Great. So, why don't you go by the bank, and I will drop off the bulletin?
Peg: So no one's gonna answer the phones?
Mary: Fine. You just sit there, and I'll go and do everything.
Peg: Sweet. Oh, today's a stumper. Is "nipto" a word?
Mary: You know what? This is why I was taking charge of everything. Because if I don't, nothing will get done.
Peg: Oh, it's "pinto". [laughs]
Mary: This is exactly what I'm talking about.
Peg: Guess what, Mary. Things were getting done long before you got here.
Mary: I just want everything taken care of for Pastor Jeff.
Peg: Or you just like thinking you're better than everybody.

Pastor Jeff: Isn't he the cutest?
Mary: He sure is.
Peg: Oh.
Pastor Jeff: Yeah, he's an angel. He's just happy all the time... morning, afternoon, middle of the night, 2:00a.m., 3:00a.m., all the a.m.'s, really.
Peg: Dip the pacifier in some whiskey, put him right out. But don't use the good stuff. They can't tell the difference.

Sheldon: Why are you taking that down?
Missy: It's time to grow up.
Sheldon: Leave it there.
Missy: You don't even like Cyndi Lauper.
Sheldon: No, but it's part of my daily routine. Every morning I wake up, look over there and wonder, "Why is she standing like this?"
Missy: Too bad. It's my room.
Sheldon: It's my room, too.
Missy: Yeah, and I don't get a say in any of your stupid posters.
Sheldon: These are the smartest men who ever lived, so if anyone's stupid, it's you for saying that.
Missy: Shut up!
Sheldon: You're very irritable. This might be why you're having boy problems.
