Leonard: That was really intense.
Penny: Well, now we know, next time we go to the farmers' market, the order is petting zoo first, then buy vegetables.

Penny: I can't believe you were testing me against a chimp.
Sheldon: Excuse me, Amy was testing you. I was rooting for you. Good job on that banana box, by the way.

Sheldon: The answer is cuddly soldiers with big flat noses. Moving on.

Amy: You really went your entire life without anyone saying I hate you to your face?
Penny: Yeah.
Amy: I'd say it now, but look at those cheekbones.

Leonard: Do you really want him to write back?
Sheldon: I do. And no matter how he responds, I'm going to destroy him with a picture of a bored cat saying "Oh, really?"
Leonard: Mee-wow.

Raj: Oh, you bought cookies?
Sheldon: Yes, fig newtons. I was going to ask which scientist both helped to discover calculus and had a famous cookie named after him. And then after someone said Newton, I was going to tell them they're wrong. The cookies are named after a town in Massachusetts. And then I'd throw the cookies away.

Bernadette: Have you ever seen a body so fine?
Amy: We had some pretty hot corpses in my anatomy class but none of them moved like that.

Sheldon: It's like when I thought there was possum in my closet. Did I sit around wondering? No, I sent Leonard in with a pointy stick and a bag.
Leonard: I killed his chewbacca slippers.

Sheldon: I miss Stuart's place. All this loud music and exposed brick, is this a comic book store or a rave at the third little pig's house?

Penny: I brought coffee. I wasn't sure what you like, so I got a regular, a cappuccino and a chai tea. Since you like Raj, I thought you might be into that.

Sheldon: Look, I am simply going to defend our work, scientist to scientist. And, failing that, suggest that his mother enjoys a string of both human and non-human lovers.

Leonard: "Upon review, I've changed my mind about the Cooper-Hofstadter hypothesis that space-time is like a super-fluid. In fact, it's inspired me to come up with my own theory. Maybe space-time is like two clowns with their heads in a bucket. Much like Cooper and Hofstadter."

Amy: Why? What did I do?
Bernadette: I'm sorry. I had to get the spotlight off me, and tearing down other women is part of my pageant training.

Howard: So it's settled. The fate of Doctor Who's TARDIS will be decided by a Game of Thrones-inspired death match on the battlefield of Thundercats versus Transformers.

Raj: Hey, I got you a little gift.
Bernadette: Oh, that's a lot of Girl Scout Cookies.
Raj: You know me. I'm from India. I can't resist children begging.
