Pastor Jeff: Because the first day had just begun.
Sheldon: So, before the Big Bang?
Pastor Jeff: There was no Big Bang. There was only the Word.
Sheldon: Was the word "kaboom"?

Mary: That's enough. Now, let's pray.
Sheldon: A moment please.
George Sr.: Hmm.
Mary: Leave him be.
George Sr.: He can hold hands with his family. It won't kill him.
Sheldon: We don't know that.

Ms. MacElroy: What?
Sheldon: Also in violation of the grooming code on page 48, article five, subsection B, you have a bit of a mustache.

Ms. Fenley: You have perfect pitch.
Sheldon: Okay.
Ms. Fenley: Sweetheart, you should really pursue music.
Sheldon: No, thank you. Musicians take drugs. Is there a faculty restroom I could use?

Sheldon: [on the phone] Hello, First National Bank. I'd like to speak with a loan officer. It's regarding a second mortgage on my home. My name is Sheldon Lee Cooper. Sure, I'll hold. Oh, I hate hold music.

Sheldon: Whoa. That girl just took a book on geostatistics.
Tam: Yeah, so?
Sheldon: That's not required reading for any science course.
Tam: Maybe she wants to squash a spider with it.
Sheldon: No, look, she's reading it. Who is this mystery woman?
Tam: Should we invite her to have lunch with us?
Sheldon: I don't know. So far, it's just been you and me, and we know that works. Do we really want to mess with success?
Tam: We could think of it as an experiment.
Sheldon: Oh, you do know how to push my buttons.

Sheldon: Now we need to put in a name before we start.
Meemaw: What are you thinking?
Sheldon: We should combine the letters in our two names, Sheldon and Meemaw.
Meemaw: Like, uh, ShelMaw?
Sheldon: No, using all the letters, like Emelda Showmen.
Meemaw: Did you just do that in your head?
Sheldon: Yes, why?
Meemaw: Never mind, just put it down.

Sheldon: I was exploring dimensional kinematics.
George Jr.: Admit it. He's adopted.
Sheldon: How can I be adopted when I have a twin sister? Think, monkey, think.

Sheldon: [observing the older kids outside the high school] Oh dear.

Mary: Everybody excited to start school Monday?
Sheldon: I am.
Missy: I guess so.
Mary: Georgie? Freshman year, that's a big deal.
George Jr.: How can I be excited when he's gonna be in the same grade as me?
Sheldon: Don't worry, Georgie. I'm not planning on being in the ninth grade for very long.

Tam: Is that any good?
Sheldon: I'm afraid not. I failed to make a single friend.
Tam: That sucks. I have a tough time making friends, too.
Sheldon: The worst part is, it was important to my mom.
Tam: My parents pressure me about making friends all the time.
Sheldon: So you understand what I'm going through.

Sheldon: You're sitting in my spot.
Tam: Why is it your spot?
Sheldon: It's complicated. Just move.

Sheldon: I want to understand God. Can you help me?
One: Did you not hear what we just said?
Zero: It's a binary universe.
One: God is yes and no.
Zero: Left and right.
One: On and off.
Zero: Something and nothing.
One: Positive and negative.
Zero: Male and female.
One: Light and dark.
Sheldon: But why is there evil and suffering?
Zero: Well, without evil and suffering, there is no good and happiness.
Sheldon: Oh, sure. Binary.

Dr. Gilbert: So, those pain meds should already be kicking in. Then my buddy Gary here is gonna administer the gas, which'll help you sleep. And once you're under, we'll make a little incision and snatch that guy right outta there. Any questions?
Sheldon: Yes. What kind of doctor says, "Snatch that guy right out of there?"
Dr. Gilbert: Just trying to put you at ease.
Sheldon: It didn't work. Where did you go to medical school?
Dr. Gilbert: University of Nebraska.
Sheldon: Uh-oh. Did you at least graduate with honors?
Dr. Gilbert: Top of my class.
Sheldon: Have you had any alcohol in the last 24 hours?
Dr. Gilbert: Not a drop.
Sheldon: How much sleep did you get last-
Dr. Gilbert: Gary, can we-
Gary: Got it. Just relax and start counting backwards from 100.
Sheldon: Wait, Gary, where did you study anesthesiolo-

Nurse Robinson: Here you go. One O.J.
Sheldon: I see pulp.
Nurse Robinson: No, you don't. I strained it with a paper towel.
Sheldon: Now all I can taste is towel. And pulp.

Mr. Givens: All right. Well, I'll see you on Monday.
Sheldon: Wait. Would you like to sign my petition against Happy Hearth Home Bakeries?
Mr. Givens: Well, what have they done?
Sheldon: They're making their bread faster and cheaper to save money.
Mr. Givens: That's terrible.
Sheldon: It is. Would you like to sign?
Mr. Givens: I would.
Sheldon: Excellent.
Mr. Givens: I'll get you on the way out.
Sheldon: Thank you. Well, that's one.
Meemaw: Yeah.

George Sr.: Should we get started?
Malcolm Green: Yes.
Adult Sheldon: I realize some people may find the ins and outs of tax law a little tedious, so allow me to spice this story up. Instead of an audit, imagine this is a showdown between two warriors in the most brutal and exciting form of combat there is... chess. Am I the only one who just got chills?
[fantasy:]
Malcolm Green: Let's start with the business deductions from Schedule A on the tax return dated 1989.
Adult Sheldon: I know, bold opening move. Don't worry, I came to play.
Sheldon: Happy to. I've got those receipts right here. Dated, highlighted... and itemized.
Adult Sheldon: Told you. For the next three hours, we battled it out. Two mighty brains locked in mortal tax code combat.
Malcolm Green: Justify this expense.
Sheldon: Our AGI was less than $50,000.
Malcolm Green: Improper classification.
Sheldon: Rolled over from the previous fiscal year.
Malcolm Green: The receipt has barbecue sauce on it.
Sheldon: Dad.
George Sr.: Sorry.

Sam: This is so unfair. You get so much more than every other student.
Sheldon: Fair isn't everyone getting the same thing. Fair is everyone getting what they deserve.
Sam: Sheldon, that arrogant attitude is why no one sits with you in class or lunch or ever.
Sheldon: Well, I like to think that they're maintaining a respectful distance out of deference to my intellect.
Sam: No. That's not what they're doing. They're avoiding you because you're an entitled brat who thinks that you're better than everybody else.
Sheldon: So, I should just pretend I'm less intelligent than I am?
Sam: You should realize that there are more important things in life than how smart you are.
Sheldon: Well, I'm also cute as a button, but it seems shallow to say it. [an exasperated Sam walks away] You could say it.

Mary: See? Happy Hearth Home Bakeries, just like always.
Sheldon: Well, something is rotten in the state of Denmark.
Mary: What?
Sheldon: That's Shakespeare, Mom.
Mary: Great.

Sheldon: Uh-oh.
Missy: What?
Sheldon: Listen to this. "French philosopher, mathematician and physicist, Blaise Pascal, argued a rational person should believe God exists because you have everything to gain if you're right, and nothing to lose if you're wrong."
Missy: Sounds right.
