Sheldon: Were you under the impression that Leonard has no complaints about you?
Penny: Like what? Yeah, yeah, I see you, you're making a little check sign in the air, I got it, just hold your horses. What does Leonard complain about?
Sheldon: Your driving, the plethora of stuffed animals on your bed that stare at him during your amorous activities, your constant tardiness, your singing.
Penny: My singing?
Sheldon: That's actually from my list, but Leonard would be a fool if he didn't agree with it.
Penny: Okay, if Leonard has so many problems with me, why hasn't he just said so?
Sheldon: Because, according to him, you're oversensitive and have a temper.
Penny: Oh, really? Well, then, do me a favor and tell Leonard that he can drop dead!
Sheldon: And she wonders why she's constantly under-tipped.

Leonard: Hey. We're, uh, going to the movies.
Sheldon: No, we're not. We're standing in the hallway, suffering through an awkward encounter.
Leonard: Hang on. They're showing a new digital print of Time Bandits, you wouldn't want to come, would you?
Penny: Not really, no.
Sheldon: All right, invitation pointlessly offered, invitation declined as expected, everyone's civil, nobody's fighting. Have a nice evening.

Penny: All right, five. One, two, three, four, five. Oh, wow, look at that, my Department of Defense research grant is renewed.
Sheldon: Oh! Great roll! Now you can demolish your Soviet-style cyclotron and build the large Hadron Collider.
Penny: Yay.

Sheldon: Come on, come on, we're late.
Leonard: Calm down, we'll make the movie.
Sheldon: I believe my alarm is appropriate, given the situation. The movie starts in 17 minutes, which means we'll need to make all the lights on Colorado Boulevard, plus skip the concession stand, and pre-show urination.

Sheldon: Leonard! Stop the car!
Leonard: What?
Sheldon: I can't listen to the two of you fight anymore.

Sheldon: Hey, I thought of a game we can play in the car.
Leonard: I don't want to play a game, Sheldon.
Sheldon: It's called Scientists. Now, I will name three scientists, then you will put them in order of the size of their contribution to their respective fields. To make this game even more compelling, you must consider only the contribution of the man to the field, not the validity of the field itself. For example, Abu Musa Jabir ibn Hayn made a greater contribution to the discredited field of alchemy than Halbert Vanderplatt made to neurobiology. Okay, ready to have some fun?

Penny: Sheldon, come in.
Sheldon: Thank you. I'd like to make a sandwich, but I'm out of bread.
Penny: There's some in the fridge.
Sheldon: You shouldn't keep your bread in the refrigerator. Staleness is caused by crystallization of the starch molecules, which occurs faster at cool temperatures.
Penny: On Earth, we say thank you.

Sheldon: So Leonard, how goes the mimesis?
Leonard: Mimesis?
Sheldon: You know. Mimesis. An action in which the mimic takes on the properties of a specific object or organism. Mimesis.
Leonard: What the hell are you talking about?
Sheldon: I'm attempting to communicate with you without my meaning becoming apparent to those around you. Let me try again. Have the indigenous fauna accepted you as one of their own? Nudge, nudge, wink, wink.

Howard: I brought you a little gift. New kite.
Raj: The kite you made me lose was an authentic Patang, an Indian fighting kite that my brother sent to me from New Delhi. It took me a day to put together and two days to paint. This is Hello Kitty.
Howard: Yeah, but it comes with a little coin purse. Does a Patang?

Leonard: Go! Go! Go! Go, go, go, go! Yes! Are you people watching this? Is this amazing or what?
Penny: Sweetie, that's a highlight from the '98 championship game.
Leonard: Oh. Did not know that.
Penny: How much beer have you had?
Leonard: None. Why?
Penny: Oh. I was just kind of hoping you were drunk. Now we're back live.
Leonard: Okay, yeah. I can see the difference.

Sheldon: Yeah, yeah. All right, Poindexter, sit down, shut up and listen.
Leonard: I'm sorry?
Sheldon: That's how my father always began our football conversations. And if you'd like, after the game, I'll take you outside and teach you how to shoot close enough to a raccoon that it craps itself.

Sheldon: Hold on I believe that social convention dictate you not arrive empty-handed. Would you like to bring some Cylon toast?
Leonard: Yeah, no, I'm trying to fit in, not get laughed at.
Sheldon: What's funny about Cylon toast?

Sheldon: Is that what you're wearing to watch football at Penny's?
Leonard: What's wrong with a football jersey?
Sheldon: Nothing. That, however, appears to be a football cocktail dress.

Leonard: When are you going to stop making Cylon toast?
Sheldon: When I have enough to destroy all the human toast on the battlestar known as Galactica.

Penny: Well, then why don't you come over next Saturday and watch the game with us?
Leonard: Another football game?
Penny: They have them every week.
Leonard: Did not know that.
Leonard: Sure, sure, just I don't know much about football.
Penny: Oh, that's okay. A lot of the guys' girlfriends don't know football. They just kind of drink and talk in the kitchen.
Leonard: Great.
