Sheldon: Well, you can add Jerry's Junction to the list of train stores Sheldon Cooper will never set foot in again.
Leonard: Rough night, Casey Jones?
Sheldon: You don't know the half of it. It was billed as a lively give-and-take on the merits of model train sizes. But it was actually a set-up to intimidate weak-minded spineless rubes into buying H-O starter sets.
Leonard: What's in the bag?
Sheldon: I don't want to talk about it. But it's not a spine,I'll tell you that.

Leonard: Ready.
Penny: Aww, so handsome. Like James Bond.
Sheldon: Better than James Bond, because he's tinier!

Sheldon: I've been sitting in garbage!

Amy: Kiss me where I've never been kissed before?
Sheldon: You mean like Salt Lake City?

Sheldon: If your video's frozen try re-setting the TCP/IP stack.

Sheldon: Oh, Leonard, there you are. I need you to check my head for chair lice.
Leonard: I did it last night, I'm not doing it again.
Howard: Just his head, right?
Leonard: I don't want to talk about it. You didn't catch bugs from Penny's chair.
Sheldon: Yes, I did. And now they're cavorting at the base of my hair follicles, like dancing hippies at the Redwood National Forest.
Leonard: Sheldon, you do this all the time. You fixate on some crazy idea and then blow it way out of proportion.
Sheldon: Name one time I have ever done that.
Leonard: How about the time you put GPS trackers in your garbage because you were convinced that North Korean spies were stealing your doodles? The chicken nuggets you were sure were human nuggets. The strangely shaped cloud that was following you around town. The time you put on my shirt by mistake and were convinced that you started growing again.
Sheldon: I said name one. You really need to work on your listening skills.

Leonard: You know, some people might say that it's great that we're trying to make things work long distance. They'd say things like, love is stronger than the miles between you.
Sheldon: When I rise to power, those people will be sterilized.

Sheldon: I miss the days when your romantic partners could be returned to the video store.

Sheldon: Please let me know when you and your girlfriend are done hogging the bandwidth for your self-abuse. I'm trying to stream a movie on Netflix in here.

Sheldon: What are you doing?
Leonard: Oh, uh, Priya's calling in a few minutes on Skype, and we are gonna have a dinner date.
Sheldon: It’s eight o'clock in the morning in Mumbai. How can she have dinner?
Leonard: Fine, whatever. Priya will be having breakfast.
Sheldon: All right, so technically it's not a dinner date. I suppose you could call it a, uh, dinfast date. But if you did, you'd open yourself to peer-based mocking, such as, "Hey, Leonard, how was your dinfast with Priya last night?"
Leonard: That doesn't sound like mocking.
Sheldon: You didn't let me finish. Dinfast (rolls eyes).

Sheldon: Are those soy-based candles?
Leonard: I don't know. Why?
Sheldon: Paraffin candles may contain carcinogens. Unless lung cancer is the ambiance you were going for at your dinfast. Dinfast (rolls eyes).

Leonard: Listen, I don't want to be rude, but Priya's gonna be calling any minute, so...
Sheldon: Oh, yes, Priya. Leonard, you know I make a point of never interfering in your personal affairs.
Leonard: Yes, I've always admired that about you.
Sheldon: As well you should. But I'm going to make an exception here.
Leonard: Oh, good.
Sheldon: Priya has moved back to India to pursue her law career. Instead of desperately trying to keep this intercontinental relationship alive, you could use that time to take up a hobby.
Leonard: A hobby?
Sheldon: Yes. I read recently about a fellow in Kansas with an enormous ball of twine. I bet you could give him a run for his money.

Leonard: You video-chat with Amy all the time. How is this different?
Sheldon: Don't you like Amy?
Leonard: Of course I like Amy.
Sheldon: Well, there's the difference.

Sheldon: Thanks for letting me stay here while Leonard Skypes with his girlfriend.
Penny: Oh, it's no problem. It's actually kind of nice. You reading, me reading. We're like an old married couple.
Sheldon: If we were an old married couple, the wife would serve iced tea and snickerdoodles.
Penny: I don't have iced tea and snickerdoodles.
Sheldon: A good wife would go to the store.
Penny: I want a divorce.
Sheldon: Good. On the way to see the lawyer, pick up some tea and cookies.

Sheldon: I must say, I am enjoying your new chair.
Penny: It's great, isn't it?
Sheldon: It is. Aligns the lumbar, cradles the coccyx, balances the buttocks. This is a chair worthy of the name.
Penny: What name?
Sheldon: Chair.
