Dr. Linkletter: [on answer phone] This is Grant Linkletter. I'm not home, please leave a message.
Sheldon: [leaves a message] Dr. Linkletter, Sheldon Cooper. I haven't heard back from you. I hope everything went well with Dr. Sturgis. Perhaps you two got caught up discussing physics. Time does fly when you're having fun.

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.

Sheldon: But why are you wasting your time here when you could be doing science?
Dr. John Sturgis: I told you, I'm happy here.
Sheldon: How could you be happy? You have a doctorate in physics, and you're sticking labels to a case of beans.
Dr. John Sturgis: I had to work here a month before they let me use this thing. And yet, I could go buy a real gun on my lunch break. Ha! Texas, huh?
Sheldon: But don't you miss trying to unlock the secrets of the universe?
Dr. John Sturgis: Sheldon, I spent my life chasing theoreticals. Here, I have tangible accomplishments and I get to listen to relaxing Top 40 music. Do you know this band, Air Supply? They're terrific. [sings] ♫ I'm all out of love ♫ ♫ I'm so lost without you ♫ ♫ I know you were right ♫ ♫ Believing... ♫

Georgie: [o.s.] Did you like school?
Dale: Hated it. I quit and I joined the Army.
Georgie: [o.s.] How was that?
Dale: Less girls, more getting shot at.
Georgie: [enters] Well, at least you made it out alive.
Dale: Well, then I got married. Made me kind of miss getting shot at.
Georgie: Have you ever been happy?
Dale: Ooh, let's see. No.

Dr. Linkletter: So what do we do about it?
Dr. John Sturgis: We sing.
Dr. Linkletter: What do we sing?
Dr. John Sturgis: [sings] ♫ When you're too old to work ♫ ♫ And you're too young to die ♫ ♫ Who will take care of you? ♫ ♫ How will you get by? ♫ ♫ When you're too old to work ♫ ♫ And you're too young to die ♫ ♫
Dr. Linkletter: I don't think I know that one.
Dr. John Sturgis: Hmm. Do you know "Lollipop"?
