Leonard: Hey, Stuart, I need to talk to you.
Stuart: Sure, what's up?
Leonard: I think I gave you bad advice about Penny, and I want to apologize.
Stuart: No, your advice was great.
Leonard: It was?
Stuart: Yeah, going slow really worked.
Leonard: You're kidding. Never worked for me.

Penny: Morning. What’s up?
Leonard: Nothing. We just pulled an all-nighter trying to fix a zero-gravity ... pasta maker.

Raj: (Reading Howard's tweet) I am so lonely and horny, I may open this $20 jar of peanuts and end it all.

Penny: Mmm, what smells so good?
Sheldon: That is the intoxicating aroma of Kadhai Paneer. A perfect culinary representation of the freedom this evening holds. Not only is it Indian cuisine, which Koothrappali loathes, it contains a generous helping of peanuts, which would reduce Wolowitz to a wheezing 97-pound blister. And finally, its main ingredient is paneer, a farmer's cheese that would cause Leonard to render any room uninhabitable within minutes.

Raj: What do you say, Howard?
Howard: I say Vegas baby!
Raj: What are you gonna tell your mother?
Howard: Sea World baby!

Hooker: What's your name?
Raj: Rajesh Ramayan Koothrappali.
Hooker: Hello Rajesh Ram...Hello Rajesh.

Penny: Hang on, I think the emergency key is around here somewhere.
Sheldon: We have a bowl. Our keys go in a bowl. You should get a bowl.
Penny: So, how did the beautiful mind of Sheldon Cooper forget his key in the first place.
Sheldon: I left them in the bowl.

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!"

Leonard: What were you doing at Penny's?
Sheldon: Well, we had dinner, played some games, and then I spent the night. Oh, and you'll be happy to know that I now have a much better understanding of 'friends with benefits.'

Wolowitz: Raj, there's no place for truth on the Internet.

Raj: What's wrong with you dude, that woman was all up in my jammy.
Leonard: Okay, I hate to break this to you and whatever your jammy is, but, I'm pretty sure she is a prostitute.
Raj: What? No.
Leonard: Okay, let me put it this way, in your entire life, how many gorgeous women have walked straight up to you in a bar and asked if you wanted to party.
Raj: Maybe I can save her.
Leonard: Maybe, but I'm guessing it will cost you about $500 an hour to try.
Raj: It was lovely meeting you, best of luck in your future endeavors.

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

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: Sing Soft Kitty.
Penny: That's only for when you're sick.
Sheldon: Homesick is a type of being sick.
Penny: Come on. Do I really have to?
Sheldon: I suppose we can stay up and talk.
Penny: [sings] Soft kitty, warm kitty, little ball of fur. Happy kitty, um…
Sheldon: Sleepy kitty.
Penny: Sleepy ki…
Sheldon: No. Start over.
Penny: [sings] Soft kitty, warm kitty, little ball of fur. Happy kitty, sleepy kitty, purr, purr, purr.

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.
