Mary: How about you all come work at our house?
Sam: I guess if that's our only option.
Mary: It'll be fun. I'll make food. You can even bring your laundry.
Keith: That actually would be great.
Sheldon: Now this man's soiled underpants will be in my kitchen. Thank you.

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.

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.

Meemaw: All right, come on, let's talk about something else.
June: Okay.
Dr. John Sturgis: A lot of people here like to talk about the game.
Meemaw: Really? You speak sports now?
Dr. John Sturgis: I sure do. Check this out. Hey, ref! I suggest you go back to referee school and this time pay attention in class!
Man #1: You tell him, Doc.

Dr. John Sturgis: What are you doing here?
Meemaw: Me? What are you doing here?
Dr. John Sturgis: Well, this is where I hang out now. I grade papers, I chat with the other patrons. The people who like to bet on football rub my head for luck.

Keith: How about we work in my dorm tomorrow?
Mary: Um, I don't know if a dormitory is the right environment for someone his age.
Sheldon: If you're worried about the beer-drinking, Dad has thoroughly desensitized me.
