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.

Principal Petersen: Our next young speaker needs no introduction, but that didn't stop him from writing one and making me read it. [laughter] "Fun fact." [audience groans, murmurs] I hear you. "The word 'valedictorian' is from the Latin 'valedicere,' meaning 'to say farewell.' It is primarily used in the United States, Canada, the Philippines and Armenia." Maybe that fact's more fun in Armenia. Please welcome your valedictorian, Sheldon Cooper.
Mary: Yay, Shelly!
Sheldon: Hello. I'm not very comfortable speaking in front of crowds. But there's a technique to reduce stage fright by focusing on one person in the audience and delivering your speech just to them. That's what I'll be doing today. If it weren't for this person, I wouldn't be here right now. They've taught me a lot, and it's by their example that I found the courage to move forward into this new and exciting chapter of my life. Missy... ...this is for you. Change can be scary, but I know we're going to be fine... ...because like you said, "It's okay to be scared. We just have to do it anyway." So if any of my fellow graduates are nervous about the future, know that you're not alone. I suggest you all try to be as brave as my twin sister. That's my plan. Missy, I wish I could give you advice about middle school, but I was so smart, I skipped it. If you make it to high school, we'll talk. Thank you. [applause]

Mary: Let's say grace.
Sheldon: Hang on, safety first. [puts mittens on]
George Jr.: When are you gonna get over that?
Sheldon: I would think recent events would make you value protection.
Mary: Enough.

Missy: What's it like to not believe in God?
Sheldon: It's great. Big fan.
Missy: Are you ever afraid you're wrong?
Sheldon: About religion? Never. About other things? Also never.

Dale: Well, you're not a fan of doctors, huh?
Meemaw: They never have good news. They just want to find something wrong.
Dale: It's kind of their job.
Meemaw: If something's wrong with me, I don't want to know about it.
Dale: That's dumb.
Meemaw: No, it's not. If I'm gonna drop dead, I'd rather do it quick and leave lookin' good.

Meemaw: I'll have the rib eye, medium rare.
Waiter: And for you?
Dale: Uh, just the house salad, please.
Waiter: Very good.
Meemaw: House salad? You watching your figure?
Dale: I have a physical tomorrow.
Meemaw: Oh, so your plan is to start eating healthy now?
Dale: Can't hurt.
Meemaw: It ain't gonna undo years of red meat and beer.
Dale: I'm not trying to undo it, I'm just trying to hide it under some lettuce.

Adult Sheldon: I'm very much a creature of habit. Perhaps it's a trait I got from my father. Every night he would go through the mail, and every night, like clockwork, he would get very cranky.
George Sr.: Damn bills.
Mary: George.
Adult Sheldon: You'd think he'd get used to it, but night after night it upset him all over again.
George Sr.: Jury duty? Son of a...
Mary: George.
Adult Sheldon: It was complicated. I didn't like seeing him upset, but what can you do? I love consistency.
