Mary: So he's really good to graduate?
Principal Petersen: He sure is. I got to tell ya, usually when kids leave school after two years, it's not for college. It's for prison or pregnancy.
George: Well, between Georgie and Missy, we may hit the trifecta.
Mary: George!
George: Well, I'm not rooting for it. It's just a thing that could happen.

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: Do you think I can make it from one end of the college campus to the other in under ten minutes, including a bathroom break?
Mary: I don't know. How important is the bathroom break?
Sheldon: Very. The class schedules are designed for fully-grown bladders, and mine is child-sized.
Mary: Then don't put your classes so close together.
Sheldon: Well, it's either this or I move my labs to Tuesday afternoons.
Mary: Is that bad?
Sheldon: Yes. That's when Professor Proton is on.
Mary: Well, we'll tape it, and you can watch it later.
Sheldon: But what if I have a lot of homework and can't get to it until the next day and one of the kids in my class spoils the episode for me?
Mary: Sheldon, has anyone ever spoiled Professor Proton for you?
Sheldon: No.
Mary: Has anyone even talked to you about Professor Proton?
Sheldon: Do you count?
Mary: No.
Sheldon: Then no.

Sheldon: Just think. You'll have this table all to yourself.
Tam: Actually, I joined the jazz band. Those guys have their own table in the cafeteria.
Sheldon: Oh.
Tam: They're pretty cool. The drummer's even got a goatee.
Sheldon: Well, I'm glad I knew you before you became a heroin addict.

Adult Sheldon: Later that day, we had a graduation party for me and my sister. I don't normally care for parties, but this one wasn't so bad.
Mary: Who's ready for cake?
Missy: Me!
Dale: Hey, should we say grace?
Mary: Heck, yeah! Let's hold hands.
Meemaw: Oh, cool. Let's say grace.
Adult Sheldon: Dale invited Jesus to the party, and while he wasn't on my guest list, it was okay because it made my mom happy.
Mary: And bless our friends and family...
Adult Sheldon: In fact, it was the best graduation party I had ever been to, until the one we had for my son, Leonard Cooper.
All: Amen.
Missy: Cake!
Adult Sheldon: I wanted his name to be Leonard "Nimoy" Cooper, but Amy wouldn't let me.
Amy: Be happy I let you name him Leonard!
Adult Sheldon: Okay, okay!
Amy: Love you.
Adult Sheldon: Love you, too.

Georgie: Hey, can I ask my girlfriend to the prom on TV? It would blow her mind.

Adult Sheldon: I ended up using the class goggles that day and did not get eyebrow lice. But eight months later, I did contract a mild case of pink eye. Were the two events related? This scientist says yes.

Sheldon: I was a little worried about missing Professor Proton, but I'm going to tape it and watch it at night. Once I'm in college, can we push my bedtime to 8:30?
Mary: Let's talk bedtime when we're not on the news, honey.
Sheldon: I'm sure it'll work out since I have all summer to recalibrate my bathroom schedule.
Mary: Let's not talk about that, either.

Kimberly: We're here with the Cooper family. Mary, George and eleven-year-old Sheldon, who's going to be Medford High School's valedictorian. Mom and Dad, you must be so proud.
George: Oh, very proud.
Mary: But we're proud of all of our children.
Sheldon: She has to say that.

Sheldon: Where are my safety goggles?
Tam: I don't have no orange today.
Sheldon: No, I have a lab later.
Tam: Just use the room goggles like everyone else.
Sheldon: And risk eyebrow lice? They don't just like head hair, Tam. They must be in my locker. [walks off] Don't eat my fluffernutter!
Tam: I won't. [eats fluffernutter] Mmm. [imitates Sheldon] "Don't eat my fluffernutter."

Adult Sheldon: I never understood why kids didn't like being sent to the principal's office. I thought it was great.
Principal Petersen: Sheldon, you are a remarkable young man.
Sheldon: Thanks, and you're a remarkable old man.
Mary: Sheldon.
George: So you sure he's got all the credits he needs?
Principal Petersen: Yeah, between his coursework and his AP tests, he's met all of his academic requirements. He even managed to get a good grade in P.E.
Sheldon: I earned extra credit snitching on kids who were smoking behind the equipment shed.
Principal Petersen: I don't have to buy cigarettes for a year.

Principal Petersen: One other bit of business. Since you're graduating early, and you're top of the class, that makes you our valedictorian.
George: Way to go, buddy!
Mary: I'm so proud of you, baby.
Sheldon: You seem surprised.
Mary: Well, it's quite an accomplishment.
Sheldon: Being top of the class in this school? I don't think so.
Principal Petersen: We're really gonna miss you.

Sheldon: I imagine my leaving will be hard for you.
Tam: Oh, yeah, being best friends with a little kid really boosted my game with the ladies.
Sheldon: Makes sense. I'm a conversation starter.

Dale: [sighs] All right, let me start by saying that I owe you an apology.
Meemaw: You can finish with an apology, too.
Dale: I'm sorry we had a fight. I'm... I'm really sorry I lost my temper, and I'm very sorry that I took it out on Georgie.
Meemaw: That wasn't great.
Dale: But I want you to know that I'm trying to change.
Meemaw: 'Cause that's what people do... they change.
Dale: I mean it. You know, I'm tired of being a cranky old bastard.
Meemaw: It's tiring for everybody else, too.
Dale: Would you please?
Meemaw: Sorry. Go ahead.

Sheldon: Dad, you need to take me home.
George: Why? What's the matter?
Sheldon: I don't have my safety goggles. Let's go.
George: Sheldon, I'm busy.
Sheldon: You're just watching TV.
George: I'm reviewing game tape.
Sheldon: So you know how it ends. I'll meet you at the car.
