Sheldon: Tam, I need help navigating a social situation.
Tam: I'm eating lunch with you. You think I have the answer?
Sheldon: Dr. Linkletter invited me to a lecture on robotics, but my meemaw said he's only doing it to spend time with her.
Tam: Are you asking if men do sketchy things to get dates?
Sheldon: Yes.
Tam: Well, then, I can help you. Absolutely. Last week, I told Jessica Geiger I was an extra in Karate Kid Part II.
Sheldon: Did it work?
Tam: Again, I'm having lunch with you.

Georgie: What can I say? I'm entrepreneurialistic.
Veronica: Is that a word?
Georgie: I don't know. But if you got a lot of money, you get to make stuff up.

Sheldon: State troopers. I wonder what they want.
Adult Sheldon: It turns out they wanted me. Fun fact, this was one of seven times I was brought home by law enforcement. Once, on the back of a horse.

Adult Sheldon: Having found no answers, I took it upon myself to rectify the inconsistent timeline in Lord of the Rings. J.R.R. Tolkien had a brilliant mind, but let's be honest. He was no S.L. Cooper.

Mary: You wanted to see me, Pastor?
Peg: Cop a squat. Pastor Jeff: Uh, please, have a seat. I just wanted to thank you for all the work you've done preparing for the carnival.
Mary: Anything for the church.
Pastor Jeff: I'm so glad you said that. How would you feel if... we put Sheldon in the dunk tank?
Mary: What? No.
Peg: Aw.
Pastor Jeff: But imagine how much people would pay to dunk him. We'd raise so much money.
Peg: I'm in for $20, easy.
Mary: I'm not having people throw baseballs at my son.
Pastor Jeff: They throw them at a target. He's in a cage.
Mary: No!
Peg: Boo.
Pastor Jeff: Okay. I respect your decision.
Mary: Is that all?
Pastor Jeff: Yes.
Peg: Well, damn.
Pastor Jeff: [to the heavens] I do so much for you.

George: So how'd you wind up coaching baseball?
Dale: Well, with the sporting goods store, you know, I've sponsored a couple of teams, and then this year, my grandson wanted to play, so it lets me spend more time with him.
George: That's nice. Yeah, I coach my son in football.
Dale: Sheldon?
George: Oh, God, no. Can you imagine?
Dale: You really scared me there for a second.

George: Oh, yeah. Connie's great. You can have a beer with her, watch a football game, joke around. She doesn't mind if you swear. In fact, that woman's got a mouth on her.
Dale: I have noticed that.
George: Yeah. You know, I just realized something. I got more in common with my mother-in-law than I do my own wife.
Dale: That's kind of creepy.
George: Yeah. Let's hope the beer does its job and I don't remember this tomorrow.

Adult Sheldon: Thanks to Dr. Sturgis, I had all the intellectual ammunition I needed to bring my opponent to his knees. I accused him of conflating two different interpretations of quantum theory, woefully misrepresenting Paul Dirac, and when I called him a dung beetle in Latin, I was so riled up, I almost started producing testosterone.

Lisa: [modem screeching] What's that noise?
Georgie: No idea.
Sheldon: Georgie, I need you to get off the phone.
Georgie: Hang on, Lisa. I'm helping someone with their English homework.
Sheldon: I don't have time for jokes. I need the phone line to connect my modem.
Georgie: What the hell's a modem?
Sheldon: It links my computer to an interconnected web of other computers in order to facilitate the exchange of ideas.
Georgie: That's the stupidest thing I've ever heard of.
Adult Sheldon: Sadly, that was not the stupidest thing he ever said.

Sheldon: [answering phone] Cooper residence.
Dr. John Sturgis: Hello, Sheldon.
Sheldon: Dr. Sturgis. I'd love to talk to you, but I'm right in the middle of Star Trek: The Next Generation. It's a good one. Geordi goes missing, but Wesley Crusher has a plan to use neutrinos to locate him, since they'd be visible to Geordi's visor.
Dr. John Sturgis: I was actually calling to speak to your father. But I'm glad you're having fun with your friends.
Sheldon: Hang on. I'll go get him. Dad! Phone call!
Adult Sheldon: Even though Dr. Sturgis was confused, one day, Wesley Crusher really would be my friend. Neat, huh?

Mary: And then she said she didn't want the other kids to see Billy hanging out with Sheldon.
George: That boy's only other friend is a chicken and she's worried about Sheldon?
Mary: What do we do? Tell Missy she can't go?
George: If we're only gonna let Missy go places where they want to have Sheldon, then she ain't gonna get out much.

George: Your mother won't let me have a TV in my room, so you're not getting one in yours.
Georgie: Why do you care what Mom says? You're the man of the house, what you say goes.
George: If you're not gonna take this seriously, I don't know why I'm talking to you.

Adult Sheldon: In many ways, a high school is like an academic house of horrors. There's the cafeteria, which when even freshly cleaned, maintains a subtle aroma of tater tots and throw-up. The schoolyard, where one is exposed to bullying by delinquents and attacks from above by eye-pecking demons. [bird tweets] But all of these pale in comparison to the most horrific location of all. A place teeming with the sweat and secretions from hundreds of unwashed bodies. The swimming pool.

Principal Petersen: Sorry, Sheldon. Water safety is a required part of your P.E. class.
Sheldon: But other kids use that pool. It's basically a big bowl of teenager soup.
Principal Petersen: It's out of my hands. It's a state requirement. If you don't like it, take it up with your congressman.
Sheldon: I did. He won't return my calls.
Principal Petersen: Then I guess you're swimming tomorrow. [manic laughter, thunder clap and lightning]
Adult Sheldon: Except for the laughter, the glowing eyes and the lightning, that's exactly how it happened.

Adult Sheldon: Observation is an important part of the scientific method. Darwin observed the finches, Jane Goodall observed the chimpanzees, and for some reason, Dr. Sturgis wanted to observe my meemaw's new suitor.
