Sheldon's degrees: B.S., M.S., M.A., Ph.D., Sc.D.
Penny: Hey. So you guys ready to order?
Sheldon: Since we come in every Tuesday night at 6:00 and order the same exact thing, and it's now 6:08, I believe your question not only answers itself but also stands alongside such other nonsensical queries as "Who let the dogs out?" and, uh, "How are they hanging?"
Penny: Okay. So, the usual, with extra spit on Sheldon's hamburger.
Penny: Just to be clear, when you guys say "spa," does that mean the same thing as when regular people say it?
Leonard: Pretty much. Except we keep our shirts on in the sauna.
Penny: You know, for a smart guy, you really seem to have a hard time grasping the concept "don't piss off the people who handle the things you eat."
Amy: That does seem to be a valid principle.
Sheldon: I trust Penny will adhere to the "Official California Restaurant Workers'
Solemn Oath of Ethics and Cleanliness."
Amy: I don't believe there's any such thing.
Sheldon: [To Leornard] You lied to me?
Sheldon: I need to sleep here tonight.
Sheldon: Howard is a complete and total ass, Bernadette is in Penny's bed, Amy bites, and Penny may or may not have coitus with Leonard.
Rajesh: Okay. Come on in.
Bernadette: I think all branches of science have to move cautiously these days. It's not just giant nuclear weapons that can destroy the world. As a microbiologist, I can tell you even the tiniest organisms can still tear you a new one.
Howard: Interesting. I think what you might need to know about my colleague is that though she claims her field of interest is tiny organisms, she certainly has spent her fair share of time around what we can assume was pretty massive weaponry.
Bernadette: I think Mr. Wolowitz needs to keep in mind that the past is the past. But he should know that I am the kind of girl who could get all the giant missiles she wants.
Amy: Are we talking about women wanting penises? Because I'd like to weigh in.
Sheldon: Dr. Koothrappali, would you care to join the conversation?
Rajesh: Certainly. I'd like to raise two points. Number one, I think they are talking about penises. And number two, these mimosas are kicking my little brown ass.
