Adult Sheldon: For many children, their happiest memory is the day they learned to ride a bike.
For others, it's when they got their first puppy. For me, it was the day I received a box of 57 defective smoke detectors loaded with americium-241.

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. John Sturgis: Hello, my little vicuña.
Meemaw: [chuckles] Well, hello to you, too. And more importantly, what is a vicuña?
Dr. John Sturgis: Only what I feel is the cutest camelid on the planet.
Meemaw: Well, I suppose I could ask you what a camelid is, but you're just gonna say more words that I don't know.

Dr. John Sturgis: Connie, I believe I have answers to all your questions.
Meemaw: Lay it on me.
Dr. John Sturgis: Time: the event begins at 6:00 p.m. The dress code is: business attire. Dinner will be served, but it's been suggested that we eat first, because the food is dreadful.
Meemaw: Good to know.
Dr. John Sturgis: And last but not least, a camelid is any member of the camelidae family, such as llamas, alpacas or vicuñas. You didn't ask that one, but, uh, it seemed like something you should know.

Sheldon: Why are you eating cereal for dinner?
Billy Sparks: I was hungry, and my parents are in their bedroom kissing.
