Leonard: No, I'm not going to reconsider. Your request was denied. I don't care if it helps you think; you don't need a koi pond in your office. Well, you should have thought about that before you bought the koi!
Penny: Wow. That was a little rough.
Leonard: Well, I have to be. Everyone assumes I'm just gonna give them whatever they want.
Penny: Hmm. But you're not, are you?
Leonard: No, I'm not. I mean, look at this. An espresso machine? I don't think so. Denied!
Penny: Wow, I really like this side of you.
Leonard: Really?
Penny: Yeah, just so decisive.
Leonard: Well, check this out. A standing desk. Denied!
Penny: Oh!
Leonard: If you want to stand, do it on your own time, 'cause I'm the boss.
Penny: Yeah, you are.

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?

President Siebert: So, there are some funds left in the general administrative grant, and I need somebody to decide how we should disburse them.
Leonard: Really? Wow, what an honor. Thank you. So how do I decide who gets the money?
President Siebert: How do you decide anything? Think about it with your brain, and then say it with your mouth.

Sheldon: All right, I've kept you in suspense long enough. "Dutch" is a bastardization of the word "Deutsch," meaning German.
Penny: What's German for "annoying"?
Sheldon: Nervig. Why do you ask?

Sheldon: This reminds me of a traditional Amish barn raising. With everyone pitching in.
Howard: How exactly are you pitching in?
Sheldon: I don't hear anyone else giving facts about traditional Amish barn raising.
Leonard: The rest of us are pitching in with hammers and nails.
Sheldon: Well, facts are my nails, and my voice is the hammer which pounds them through the wood of your skull.
Penny: Well, that is how it feels.
