Sheldon: [on the phone] So if I don't actually look at the letter, legally I'm in the clear? Thank you. This has been very helpful. And if in the future, you have any physics questions, Janice has my info.

Sheldon: Dad.
George: What the hell are you doing here?
Sheldon: I need to talk to you.
George: How'd you even find me?
Sheldon: It's not like you come home smelling like coffee.

George: You ready?
Sheldon: Yes.
George: Okay, we're rolling.
Sheldon: Hello, Mother. I'd like to present my case as to why I should be allowed to go to East Texas Tech next year. And I'll keep it simple so you don't get confused.
George: Stop.
Sheldon: Something in my teeth?

Sheldon: I've put together a presentation detailing the reasons why I should be allowed to go to college, and I'd like you to watch it with an open mind.
Mary: I can do that.
Sheldon: Excellent. Is Meemaw here? I smell cigarettes.

Sheldon: Thank you for this opportunity to plead my case. And I'd like to thank my cameraman and driver, Dad.
George: What, I'm not even, like, assistant director?
Sheldon: No. Sit back, enjoy.

Sheldon: I was a little worried about missing Professor Proton, but I'm going to tape it and watch it at night. Once I'm in college, can we push my bedtime to 8:30?
Mary: Let's talk bedtime when we're not on the news, honey.
Sheldon: I'm sure it'll work out since I have all summer to recalibrate my bathroom schedule.
Mary: Let's not talk about that, either.

Meemaw: What are you looking for?
Sheldon: Chest hairs. Is there any chance I'll hit puberty in the next few weeks?
Meemaw: Oh, God, I hope not. Why?
Sheldon: The campus is so big, I'll never make it from one class to another without a solid dose of testosterone.
Mary: Maybe they'll let you leave early so you'll have time.
Sheldon: But the end of the class is when I point out the teacher's mistakes. Everybody loves that.
Mary: I'd say run across campus, but I know how you feel about sweating.
Sheldon: It's the urine of the skin.

Sheldon: Dad, you're a football coach. Do you use human growth hormone to enhance the performance of your players?
George: We lost our last game sixty-three to nine. What do you think?
Sheldon: I think you should look into human growth hormone. And if you do, send some this kid's way.

Adult Sheldon: With no access to controlled substances, I was left with only one option.
Sheldon: Missy, will you teach me to ride a bike tomorrow?
Missy: Why not Mom?
Sheldon: Working.
Missy: Meemaw?
Sheldon: Old.
Missy: Dad?
Sheldon: Fat.
Missy: Okay. [Sheldon exits] I'm such a good person.

Sheldon: Left-handed knocking. Wild. [knocks three times] Georgie?
Georgie: [o.s.] What? [Sheldon enters Georgie's bed room]
Sheldon: You're left-handed. Now that I've joined your ranks, I was wondering if you could tell me what to expect.
Georgie: I don't know. To me, it's just normal.
Sheldon: But the vast majority of people are right-handed. There must be some challenges.
Georgie: It's hard to cut stuff with scissors.
Sheldon: Mom handles most of my cutting needs.
Georgie: Uh, when you shake hands, it's the wrong hand.
Sheldon: I don't shake hands. It's disgusting.
Georgie: Oh! When driving, the gear shifter's on the right side.
Sheldon: And I'm not old enough to drive. Being a lefty doesn't seem so bad. I don't know why you complain so much.

Sheldon: I may not look it, but I'm the future of physics, so just move on.

Sheldon: Dr. Linkletter.
Dr. Linkletter: Sheldon. How wonderfully early it is to see you. If you've come by for a snack, I picked you up some crackers shaped like fish.
Sheldon: I just wanted to let you know that I don't need you to babysit me. I'm perfectly self-reliant.
Dr. Linkletter: Excellent. I'm not very comfortable around children, even with your level of maturity. How old are you? Six? Seven?
Sheldon: Eleven.
Dr. Linkletter: I see. Then it's good I kept the receipt for this bottle of bubbles shaped like a bear.
Sheldon: I should get going. My philosophy class starts in a few minutes.
Dr. Linkletter: Ah, yes, the great thinkers. Socrates, Plato. Speaking of which, I got you some Play-Doh.

Sheldon: I stopped at the library today and picked up books on epistemology, Descartes's dream argument and the foundations of scientific logic. Do you know what she's going to do?
Meemaw: Rue the day?
Sheldon: The day, the night. If it's rue-able, she's going to rue it.

Professor Ericson: So we learned that the theory of knowledge poses some very serious problems.
Sheldon: [enters] Excuse me, Professor Ericson. I've done a little reading since last we spoke, and I'm prepared to show you that everything we know about science is true.
Professor Ericson: Well, I am all ears.
Sheldon: You said I couldn't truly know anything, but there is one thing that I do know. If I question, I must think; If I think, I must exist. Cogito, ergo sum: I think, therefore I am.
Professor Ericson: You're right.
Sheldon: You're darn right I'm right.
Professor Ericson: Guys, g-give it up for Sheldon. [applause] Now for a job well done... here is a flower full of sweet nectar.
Sheldon: Why would I want that?
Professor Ericson: Because you're a butterfly and this is just your dream.
Sheldon: I'm not a butterfly.
Professor Ericson: Are you sure? [laughs]
[Sheldon wakes up:]
Sheldon: It was a dream. Oh, no. [camera pans out] Help! I'm a butterfly! Nothing I know is real! Everything is a dream! Missy, help! [Missy holds a fly swatter] No!
[Sheldon wakes up:]
Sheldon: Missy, am I awake or is this a dream?
Missy: Shut up, dingus.
Sheldon: Okay, I'm awake.

Meemaw: What's this philosophy teacher's name?
Sheldon: Professor Ericson. Why?
Meemaw: I might pop in and say hello.
Sheldon: Be careful. She may make you question your most deeply held values.
Meemaw: I'm a stubborn old crank. I'll do just fine.
Sheldon: I'm a stubborn young crank, and it didn't help me.
