Sheldon: We have seven people and two cars. In the lead car, driven by Leonard, will be myself, Amy Farrah Fowler and Penny.
Amy: Yes! He had you in the other car, but I got you upgraded.
Penny: Yay.
Sheldon: She made the case that if we break down in the middle of nowhere, your Nebraska backwoods skills and brawny hands will give us the best chance to survive in the wild.
Penny: Brawny?
Leonard: They're bigger than mine.

Leonard: What would you be if you were attached to another object by an inclined plane, wrapped helically around an axis?
Sheldon: Screwed?
Leonard: There you go.

Leonard: Penny, as a scientist, my job is to figure out why things happen. But I don't think I'll ever understand how someone like me could get to be with someone like you. You know maybe I don't need to understand it, I just need to be grateful. I love you, Penny.

Sheldon: This song is never going to stop. Have you ever dealt with something so relentlessly irritating?
Leonard: That's a trick question, right?

Howard: What, I'm not hot enough for Angelina Jolie?
Raj: Id like to weigh in here: No.

Amy: Are you in the lanthanide series?
Sheldon: Amy, it's Penny's turn. Penny.
Penny: Uh, I dunno. Are you food?
Sheldon: That's not a apropos! We've already established I'm found on the Periodic Table.
Penny: Well, it's a table, right? I mean, why can't there be food on it?
Sheldon: I knew she wasn't lead car material.

Sheldon: Good morning everyone and welcome to "Science and Society". I'm Dr. Sheldon Cooper, BS, MS, MA, PhD and ScD. OMG, right?
