Leonard: Trust me, this will be just fine.
Howard: You are the authority on just fine.
Leonard: What's that supposed to mean?
Howard: (after Raj whispers to him) Yeah, exactly. Not bad, but not great.
Penny: What are they talking about?
Leonard: I don't know.
Sheldon: I know. As I'm sure you're aware...
Leonard: Duh-duh-duh-duh-duh-duh.
Sheldon: If that's Morse code, that's terrible.

Leonard: Nothing flamed out. We don't have to have sex every night, you know.
Howard: You don't have to, but it's highly recommended.
Raj: Yeah, take advantage of that window of opportunity before it slams shut on your little dinky.

Leonard: It's not a matter of opportunity. We're getting to know each other. There's a learning curve.
Howard: What's there to learn? You get naked, do nasty things to each other, then somebody makes scrambled eggs and salami. Easy peasy.

Leonard: Sheldon, dinner's here.
Sheldon: Tandoori Palace?
Leonard: No, we went somewhere new.
Sheldon: You’re good-naturedly ribbing me, aren't you?
Leonard: No, look, Mumbai Palace.
Sheldon: Why? Why would we change? We had a perfectly good palace. Tandoori Palace is our palace.

Sheldon: Perhaps what Leonard is obliquely referring to is the occurrence of some sort of sexual dysfunction.
Raj: Okay, who had Leonard gets a floppy disk?
Sheldon: Oh, a clever, albeit obsolete, euphemism for insufficient blood flow to the male sex organ.

Sheldon: As I was saying, you and Leonard had a disappointing sexual encounter. Earlier this evening, Leonard characterized it as just fine. So what you're seeing here is a continuation of the mocking that followed.
Penny: Okay. Yeah, well, I'm just gonna go eat my dinner elsewhere. Maybe an airplane headed for a mountainside.

Penny: What did you tell them?
Leonard: Nothing bad, just that last night was fine.
Penny: Fine? You said it was fine?
Leonard: Yeah, it's a perfectly good word. You put it in front of wine or dining, and you've really got something.

Penny: It was ... okay.
Leonard: Okay?
Penny: Yeah, it's a perfectly good word. I mean, you put it in front of dokay and you really got something.

Raj: What's that?
Howard: Sounds like a cricket.
Sheldon: Hang on. Based on the number of chirps per minute and the ambient temperature in this room, it is a snowy tree cricket.
Howard: Oh, give me a frickin' break. How could you possibly know that?
Sheldon: In 1890, Emile Dolbear determined that there was a fixed relationship between the number of chirps per minute of the snowy tree cricket and the ambient temperature. A precise relationship that is not present with ordinary field crickets.
Raj: How do you know what the exact temperature of the room is?
Sheldon: Under the terms of my roommate agreement with Leonard, I've had unilateral control of the thermostat ever since the sweaty night of '06.

Howard: Okay, you were right about Wolverine and bone claws, but you're wrong about the cricket.
Sheldon: Howard, don't embarrass yourself, the science chirps for itself. Humorous word play.

Raj: These methods of meditation come from the ancient gurus of India, and have helped me overcome my own fears.
Sheldon: And yet, you can't speak to women.
Raj: True, but thanks to it I am able to stay in the same room with them without urinating.

Sheldon: People of Sheldonopolis, this is your mayor. Follow me. If the children can’t run, leave them behind. Oh, the simulated horror!

Penny: Is there anything else?
Leonard: Yeah, don't let Goofy near him. He'll have nightmares and I'll have to deal with it.
Penny: What's the problem with Goofy?
Leonard: Wish I knew. He's fine with Pluto.

Sheldon: And now, as promised, the tangent. "Sheldon and the Hell Hound", or "How I Lost My Hot Dogs".

Penny: He's such an angel when he's asleep.
Leonard: Yeah. Shame he has to wake up.
Penny: I think we can do it.
Leonard: Smother Sheldon in his sleep? Wouldn't that be wrong?
