Dr. John Sturgis: We want to offer you a job.
Sheldon: And for you to wash your hands.
Toby: I already have a job.
Dr. John Sturgis: We know. We want you to do the same thing, but for more money.
Toby: Okay.
Sheldon: Really, that's all it took? Where's the loyalty?
Dr. John Sturgis: Sheldon, this is what we want.
Sheldon: I know, but what if somebody comes along and offers him more money? Is he just gonna leave us?
Dr. John Sturgis: Are you?
Toby: Probably.
Sheldon: We can hire him, but he cannot go to the bathroom alone.
Dr. John Sturgis: [offers hand] Welcome aboard.
Sheldon: Whoa, whoa, whoa. Let's hit that sink.

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]

Sheldon: Missy and I broke a lot of rules the other night, and we've received no punishment.
George Sr.: [sighs] Buddy, it's been a rough week. We're just glad you're both safe.
Sheldon: But in the absence of a divine being, society's rules are what keeps a person's morality in check.
George Sr.: Well, there you go.
Sheldon: No, y-you're not following me. If actions have no repercussions, society breaks down, everything devolves into chaos.
George Sr.: You might be overthinking this.
Sheldon: I thought so, too. Then I thought about it, and I'm not.
George Sr.: Sheldon, you had one bad night. Just let it go.
Sheldon: But... I did something wrong and I got away with it. That's not okay.
George Sr.: Buddy...
Sheldon: Socrates maintained that the man who lies to himself has an enemy living within. He's not even a person. He's just a chaos of selfish desires wrapped in an animal hide.

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.

Mary: [sighs] Well, I can take off work and look after y'all.
Meemaw: We're fine.
Mary: Fine? You're on the floor. What happens if you need to use the bathroom?
Meemaw: Depends.
Mary: Depends on what?
Meemaw: [chuckles] No, it's a joke.
Mandy: [laughs] I got it. [both laughing]
Mary: What's the joke? Tell me.

Meemaw: Let me lay here for just a minute.
Mandy: Can I get you some ice or something?
Meemaw: No, no, no. You've got to stay in bed. [exhales]
Mandy: Okay. Well, you look like the "I've fallen and I can't get up" lady.
Meemaw: That's because I have fallen and I can't get up. [laughs] Okay, it hurts when I laugh. [laughing]

George Jr.: Oh, that there's a real good one. You should get it. I'll ring it up.
Robert: I don't know.
George Jr.: Don't know? Whoopi Goldberg as a singing nun? What's there to think about?
Robert: I might be more in the mood for action.
George Jr.: She's on the run from the mob. You'll love it. I'll ring it up.
