Leonard: What's he doing here?
Sheldon: We're going to work this office situation out like gentlemen. And if that doesn't work, I'm going to poison his tea.

Sheldon: Fine. In the interest of preserving our friendship...
Barry Kripke: Were not friends.
Sheldon: Well, that's a little hard to hear, but all right.

Raj: How about you decide this with Rock-Paper-Scissors-Lizard-Spock?
Barry Kripke: What the frig is that?
Sheldon: Rock-Paper-Scissors-Lizard-Spock was created by Internet pioneer Sam Kass as an improvement on the classic game Rock-Paper-Scissors. All hail Sam Kass.

Sheldon: Hey! He did that on purpose,
Leonard: No, he didn't. Nothing that's happening here is being done on purpose. Okay, uh, forget one-on-one. Let's try a free throw contest. First person who makes a basket wins the office.
Barry Kripke: Making it too easy there, Hofstadter.
Leonard: No. No, I'm not.

Amy: Oh, what a great movie.
Penny: I cannot believe you've never seen Grease.
Amy: My mother didn't allow me to watch it. She was afraid it might encourage me to join a gang.

Sheldon: Ah, the spoils. I see why victors love them.

Amy: I'm so humiliated. I sat there the whole time that we were watching Grease, thinking you liked the painting.
Penny: I know.
Amy: I was a fool from Summer Lovin' to the very last rama lamma lamma ka dinga da dinga dong.

Penny: I should have been honest with you and told you the gift was too much.
Amy: Yes, too much. Because our friendship is fundamentally asymmetrical. I clearly like you more than you like me.
Penny: I don't think you can put a number on how much one person likes another.
Amy: I bought you a painting, that's 12 square feet in area. There's a number.
Penny: Amy, come on...
Amy: If you don't like feet, you can try dollars. The painting set me back three grand.

Penny: Okay, look, I didn't want to say this, but the real reason I took the painting down was because it made Bernadette very jealous.
Amy: Oh, my goodness, how could I have not seen that? The painting is a constant reminder that of the three of us, she is the least cool.

Howard: Why don't you just turn up the thermostat?
Sheldon: Aha! Good question. It turns out the thermostat for my new office isn't in my new office. No. It's next door in Professor Davenport's office, who is currently enjoying the hot flashes associated with menopause.

Leonard: Why is there a hole here?
Sheldon: Why is there a hole in my new office? I've narrowed it down to two possibilities: There was something in the wall that someone outside the wall wanted, or the more disturbing, there was something in the wall that wanted out.

Raj: Well, at least you finally got a window that opens. That's nice.
Sheldon: Is it? Listen.
Raj: What, you don't like wind chimes?
Sheldon: No, I hate them, but it gets worse. There it is.
Howard: The bird?
Sheldon: Yeah, It's completely out of tune with the wind chimes.
Raj: So?
Sheldon: You don't get it, do you? That's a mockingbird. Mockingbirds can change their song, which means he's out of tune on purpose. He's mocking me.

Leonard: Sheldon, relax.
Sheldon: How can I relax? My nervous system is being stretched out like the strings of a harp and plucked by holes, and birds, and wind, and the low-hanging scrotum of the difficult-to-evict Professor Rothman.
Leonard: If you're not happy, why don't you just let Kripke have the office?
Sheldon: What, and let him win? Do I look crazy to you?

Sheldon: Oh, dear. Mr D'Onofrio's in the hospital. Why do these things always happen to me?

Sheldon: When I first moved here, I was nervous about finding a new barber, so my mother had all my haircut records sent here to Mr. D'Onofrio.
Leonard: There's no such thing as haircut records.
