Missy: We could let people punch you for a buck.
Sheldon: No, all our profit would just go to medical expenses.

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.

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: 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.

Meemaw: [on the phone] But I want to be clear, this is just one of those... Whatcha call it... Uh, platonic things. We're just having dinner.
Dr. Linkletter: I'll take it. Now, would you prefer a restaurant or some good home cooking? I make seven kinds of soup.
Meemaw: I think I'll just stick with a restaurant.
Dr. Linkletter: Fair enough, but one day, you'll try my mushroom barley, and your taste buds will swoon.
Meemaw: Good night, Grant. [starts to put down phone]
Dr. Linkletter: The secret is how long I cook the onions.

Meemaw: So... this is unexpected.
Dr. Linkletter: Well, I know you like margaritas, so my first thought was a Mexican restaurant.
Meemaw: Good thought.
Dr. Linkletter: But I assumed other men had come to that same conclusion.
Meemaw: They have.
Dr. Linkletter: Which led me to Polynesian fare. I like to think of the Mai Tai as the margarita of the South Pacific.
Meemaw: You don't do anything on a whim, do you?
Dr. Linkletter: Did once, didn't like it.

George: What are you doing here?
Meemaw: I ran out of beer at home, didn't feel like driving to the store.
George: Oh, so you just waltz in and help yourself?
Meemaw: 'Bout sums it up. [hands George a beer]
George: I'm changing the locks.
Meemaw: [laughs] Cheers.
