Sheldon: I need to talk to you about the paper that Dr. Fowler and I published.
President Siebert: Send him in.

President Siebert: Look, it doesn't matter if they have popular support, we're gonna get the scientific community behind us.
Leonard: He's right, the Nobel Prize is about the work, and as your fellow scientists, we support you and Amy.
President Siebert: That's great, Scooby Gang.

President Siebert: No.
Leonard: I'm sorry, President Siebert, but I'm not taking no for an answer.
President Siebert: I speak a little Russian. Will you take nyet for an answer?
Leonard: I'm serious.
President Siebert: Oh. Well, that changes everything.
Leonard: Really?
President Siebert: Nyet.

President Siebert: Dr. Cooper, there you are. I just wanted to tell you not to worry about this Pemberton and Campbell publicity blitz.
Sheldon: Are you worried?
President Siebert: Not at all. Not even a little bit. [manic laugh]

Bernadette: Then why?
Penny: Honestly, I don't know if I'm up to it. You know, the last project I managed was my high school yearbook.
Bernadette: And?
Penny: And that was the year we didn't have one. - And? And that was the year we didn't have one. Apparently, the printers won't make them without getting paid.
Bernadette: What happened to the money?
Penny: Uh, if I didn't know then, I'm not going to magically know now.
