Sheldon: [on the phone] I don't like it here. I miss being the smartest one in class.
Dr. Linkletter: Son, if you're always the smartest, you're never learning anything.
Sheldon: Interesting. So what do I do?
Dr. Linkletter: Listen.
Sheldon: I'm listening.
Dr. Linkletter: No, that's the answer. Try doing something you're truly awful at: just shut up and listen.
Sheldon: But what if I...
Dr. Linkletter: When you're in class, listen.
Sheldon: But I could... [Linkletter hangs up]
Dr. Linkletter: Guess I should pee.

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.

Sheldon: Dr. Linkletter, I need to talk to you.
Dr. Linkletter: Great.
Sheldon: Do you think you could get me access to the telescope room? I want to search for exoplanets that could support life.
Dr. Linkletter: Are you feeling homesick?
Sheldon: Are you implying that I'm from another planet?
Dr. Linkletter: Yes.
Sheldon: Compliment accepted.

Sheldon: Now, about the telescope room, I was watching Star Trek and it got me thinking...
Dr. Linkletter: Sheldon, searching for life on other planets isn't serious science. Leave that to the tinfoil hat brigade.
Sheldon: But statistically, given the number of stars and planets, it's likely we could find one capable of supporting life. And if we did, it would be the greatest scientific discovery of all time.
Dr. Linkletter: Yes, and if I had fruit on my head, I'd be Carmen Miranda.
Sheldon: I'm not familiar with that reference.
Dr. Linkletter: She sang and danced with fruit on her head.
Sheldon: Why would she have fruit on her head?
Dr. Linkletter: I don't know, in case she got hungry. It's not gonna happen, Sheldon!

Adult Sheldon: Heidelberg is considered one of the most beautiful cities in Germany. Heidelberg Palace, the Karl Theodor Bridge, the Schloss Schwetzingen. But I couldn't care less. The only sights I wanted to see were the looks of awe on the faces of my fellow students as I demonstrated my intellectual superiority.
Sheldon: Cylinders that are smaller than ten to the minus-35 meters. [all laugh] What's happening?
Professor Salzman: You don't laugh at people saying stupid things in Texas?
Sheldon: You're darn tootin' we do. So who goofed? [laughter]
Professor Salzman: You did, dummkopf.
Sheldon: Dummkopf? You're calling me a dummy?
Professor Salzman: Class, who knows where the dummkopf went wrong? [hands go up] Mr. Ziegler.
Mr. Ziegler: He forgot to consider the Calabi-Yau manifold.
Professor Salzman: Thank you, Mr. Ziegler.
Sheldon: Wait, what's the Calabi-Yau manifold? [laughter]
Professor Salzman: Dummkopf.
Adult Sheldon: I was quickly learning not all Germans were the warm, fun-loving people I was led to believe.

Professor Salzman: [sighs] You are far behind many of your peers.
Sheldon: I have no peers.
Professor Salzman: I think they would agree. Which is why I'm going to recommend tutoring.
Sheldon: Me tutor them?
Professor Salzman: No.
Sheldon: You tutor me?
Professor Salzman: No.
Sheldon: Me tutor you?
Professor Salzman: Miss Chen.
Mei-Tung: Yes, Professor?
Professor Salzman: You have an undergraduate degree in education, ja?
Mei-Tung: Yes, sir.
Professor Salzman: Teach him.

Sheldon: Professor Salzman, I just wanted to let you know that I studied up and am now well-versed in the Calabi-Yau manifold.
Professor Salzman: Okay.
Sheldon: It was never part of the curriculum at East Texas Tech.
Professor Salzman: East Texas Tech? Sounds charming.
Sheldon: It's actually quite humid. Regardless, I'm ready to reassert myself as class leader.
Professor Salzman: Your classmates are from some of the most elite universities in the world. There is no East MIT.
Sheldon: Well, I would have gone to a better school, but I was 11, which you have to admit is pretty impressive.
Professor Salzman: Sheldon, at some point we ask of the piano-playing dog not, "Are you a dog?" but, "Are you any good at playing the piano?"
Sheldon: Excuse me?
