Sheldon: [sighs] Come on, Cooper.
Dr. Linkletter: See? He's been here since this morning. He won't leave.
Dr. John Sturgis: What do you want me to do?
Dr. Linkletter: Get him to leave.
Sheldon: Oh, good, you're both here. This will go faster with three of us.
Dr. Linkletter: Now, do it! Give him the boot.

Sheldon: Dr. Linkletter, I need to talk to you.
Dr. Linkletter: Are we in my office?
Sheldon: No.
Dr. Linkletter: Then these are not my office hours.
Sheldon: Are you using my love of schedules against me?
Dr. Linkletter: [chuckles] Oh, yes.
Sheldon: Well done.

Dr. Linkletter: Sheldon, thank you for coming in. I want to apologize for our little tiff earlier.
Sheldon: You're forgiven.
Dr. Linkletter: Oh. Great. I found something that might be of interest to you. An authentic signature from Richard Feynman.
Sheldon: Where did you get this?
Dr. Linkletter: Details aren't important.
Sheldon: Is this a restraining order?
Dr. Linkletter: Not important.
Sheldon: That's actually a really good way to get autographs. I'll have to keep that in mind.

Jim: Here we are. Grab a shovel and dig in. There you go.
Dr. Linkletter: I spent the summer in Italy once.
Georgie: Bringing back memories?
Dr. Linkletter: No.

Mary: I'm waitin'.
George: For what?
Mary: The "I told you so." 'Cause I coddled Sheldon and apparently ruined his life.
George: Oh. I'm not gonna say that. I mean, you did coddle him and I did tell ya... All right, I told you so.
Mary: Thanks for not sayin' it.

Sheldon: Hold on, should I be trying to beef up my grad school applications?
Dr. John Sturgis: The competition is fierce. It takes a lot to stand out.
Sheldon: You're my advisors, why didn't you advise me of this?
[flashback:]
Dr. John Sturgis: Sheldon, if I could offer you some advice...
Sheldon: No thank you.
[flashback:]
Dr. Linkletter: Sheldon, I have a recommendation for you.
Sheldon: I have one for you. Trim your nose hair.
[present:]
Dr. Linkletter: Do you remember that?
Sheldon: I do. It looked like a spider was living up there.

Sheldon: [on the phone] Yes, is this the Columbia summer science honors program? Excellent. My name is Sheldon Cooper, perhaps you've heard of me. Well, now you have. Anyways, it's recently come to my attention that you could be an important step in my career advancement. So, good news, I'm available. Yes, I understand I've missed the deadline, but I'm sure you can make an exception. [emotional] But I'm Sheldon Cooper.
