Adult Sheldon: Look at them over there. They got away with one transgression, and now they were clearly plotting their next.
[imaginary:]
Missy: All right, we got away with sneaking out. What should we do now?
Tonya: I say we rob the mall.
Missy: You read my mind.
Tonya: We hit the shoe store first and then the makeup store.
Missy: Smart. Those are the things we girls like.

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.

Dr. Linkletter: This will allow us to calculate the speed of sound in the liquid using the standard elements of the Einstein field equations. The answer is only correct, of course, if the density changes slowly. And to begin, we use the standard equations of thermal physics to simplify the answer... [sniffing] Wh-Wha-What am I smelling?
Sheldon: Oh, that might be my sauerkraut and knockwurst.
Ben: [raises hand] It is.
Dr. Linkletter: Why are you eating sauerkraut in my classroom?
Sheldon: I'm acclimating my body to a Germanic meat-based diet.
Dr. Linkletter: At 11:00 a.m.?
Sheldon: It's dinnertime in Heidelberg.
Dr. Linkletter: We're not in Heidelberg.
Sheldon: But I will be over the summer, so I'm trying to adjust my internal clock to the local time so I can hit the ground running mitout jet lag.
Dr. Linkletter: I got to get back to my lecture, if that doesn't interfere with your meal.
Sheldon: Oh, dinner and a show, I love it. Although... would you be a lamb and open this jar of mustard for me?
Dr. Linkletter: Here are two words you don't often hear... poor Germany.

George: You know, you seem pretty stressed out... Maybe it'd be easier if I go to Germany.
Mary: You got to be kidding.
George: Well, it might make more sense. I got the summer off. And, come on, beer and sausage? I've been training for that my whole life.

George: "Chicken boo-eh-lon"? What does that even mean?
Mary: Bouillon. It's the tiny cubes that turn into soup.
George: So, the soup aisle?
Mary: There you go.
