Sheldon: You know, I'm given to understand that there's an entire city in Nevada devoted specifically to help people like Howard forget their problems. They replace them with new problems such as alcoholism, gambling addiction and sexually transmitted diseases.

Mikayla: You want the girlfriend experience.
Leonard: Yes, yeah, exactly, the girlfriend experience.
Raj: Uh, actually, if it's not too much to ask, could we have the Jewish girlfriend experience.

Leonard: Hey, Sheldon, are you coming?
Sheldon: I'd rather have a blowfly lay eggs and hatch larvae in my auditory canal.

Penny: Alright, Sheldon, let's just calm down and we'll call the building manager, he'll come open your door, you just eat your dinner here while you're waiting.
Sheldon: Eat? My dinner? In your apartment?
Penny: Yeah, why not?
Sheldon: Sure, why not? And after the sun's down we can all pile in my pick-up and go skinny-dipping down at the creek. 'cause today's the day to stop making sense.

Sheldon: You're the milk thief! Leonard said I was crazy but I knew that carton felt lighter.

Sheldon: Okay, that's question 20, you have to guess.
Penny: Oh, God, I don't know Sheldon, are you Star Wars?
Sheldon: How can one person be a whole movie?

Sheldon: There was a tall man from Cornwall. Whose length exceeded his bed. "My body fits on it. But barely upon it. There's no room for my big Cornish head!"

Raj: It's too bad he wasn't here for that hooker. She's exactly his type. A hooker.

Leonard: Look, imagine you maintained a friendship with someone you had sex with, but you were free to date whoever you wanted.
Sheldon: I'm sorry, I can't imagine any of that.

Leonard: Howard, could I borrow some after shave?
Howard: Black case, top compartment.
Leonard: That is a lot of cologne.
Howard: First row are your musks, second is wood, leathers and botanicals, third is assorted pheromones, tread lightly.

Sheldon: We have a bowl. Our keys are in the bowl. You should get a bowl.
Penny: I just don't understand; how can beautiful mind of Sheldon Cooper forget his keys in the first place?
Sheldon: I left them in the bowl.

Raj: What happened with Leslie, why did she dump you?
Howard: I don't know. She just said Howard, momma's a rolling stone. And then her call waiting beeped and she was gone.
Sheldon: I don't understand. If you were in a non-emotional relationship then why are you having what appears be an emotional response?
Leonard: Sheldon, he obviously had feelings for her.
Howard: Of course I had feelings for her, I saw her naked for God's sake!

Sheldon: Penny.
Penny: What?
Sheldon: I can't sleep.
Penny: Maybe that's because your hole is still open.

Sheldon: So, how was your day?
Penny: Are you trying to make small talk? Oh, sweetie, you really don't have to.
Sheldon: No, it's the accepted convention. How was your day?
Penny: Well, uh, they shifted my schedule around at the restaurant so my hours are going to be a little different...
Sheldon: I'm sorry, that's not going to interest me at all, just eat.

Howard: Okay, are you from Star Wars universe?
Leonard: Yes.
Howard: Were you in the original trilogy?
Leonard: Yes.
Howard: Is there a picture of you in my wallet wearing a metal bikini?
Leonard: God, I hope not. And no, I'm not Princess Leia.
