Paige: My family never eats dinner together.
Sheldon: Why not?
Paige: My dad always manages to come home from work after we're done.
Sheldon: Hmm. My dad never misses a meal.

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: Too bad. We are going.
Sheldon: Class is starting tomorrow. I'm not going anywhere.
Mary: Sheldon, do not argue with me. You are going home.
Sheldon: Mom, the people of Germany are obsessed with rules and devoid of humor. I am home.

Mary: You understand that some people are going to be intimidated by you, because of how smart you are?
Sheldon: Or maybe they'll recognize my intellect and make me their leader.

Mary: Mom, can you make the salad?
Meemaw: Sure.
George: Hey, don't put in any of those little tomatoes.
Meemaw: Hey, I don't tell you how to impersonate a lump of clay. You don't tell me how to make a salad.

Paige: Sheldon?
Sheldon: Paige?
Paige: I'm so happy to see you. Are you happy to see me?
Sheldon: Not immediately.
Paige: That's okay. I'm happy enough for both of us.

Dr. John Sturgis: Connie, I need to apologize.
Meemaw: Oh, that's okay. Don't worry about it.
Dr. John Sturgis: No, I am worrying about it. I didn't realize that with you and I being in a relationship, me wearing your dead husband's clothes would be emotionally challenging for you.
Meemaw: All right, apology accepted.
