Penny: We watch movies with director's commentary.
Amy: Oh, my favorite. George Lucas can talk through the entire movie but I say one word and I'm banished to the kitchen.

Leonard: Interesting. We're being accused of making you do things you don't like, and here you are doing the same thing to poor Amy.
Sheldon: You should point out the hypocrisy of that.
Leonard: That's what I was doing.
Sheldon: Oh, that was wasn't clear. Do it again but this time drive it home with, "how do you like them apples, missy?"

Penny: I really thought he was going to say "let it go".

Penny: Why is everyone so concerned with us setting a date? We're committed to each other. We're happy. A ceremony isn't gonna change anything.
Sheldon: So you're never getting married? It's his whining, isn't it?
Leonard: Sheldon, I'm not a whiner.
Sheldon: It's amusing that he doesn't hear it.

Penny: Thanks for cooking.
Leonard: My pleasure.
Penny: That carrot was delicious.
Leonard: Yeah. I wish I'd fought harder for the rest of 'em.

Raj: What are you doing?
Howard: Just playing video games while Bernie does the taxes.
Raj: What are you a little kid? Is she gonna cut your dinner in to little pieces, too?
Howard: She doesn't have to. I filled up on Jelly Beans.

Penny: Shouldn't you be getting ready for work?
Sheldon: I'm not going. Would you like to know why?
Penny: You're sad about not getting any thing done last night, so you're gonna sit around and pout about it.
Sheldon: Boy, I'm not nearly as mysterious as I think I am.

Leonard: Okay, fine. Sheldon, may I please visit your fort?
Sheldon: I want to say no, but it's too glorious. Get in here!

Sheldon: I don't know why you're so surprised. If there's one thing I know after living with you all these years, it's how to compromise.

Amy: What do you say? It sounds kinda perfect.
Penny: It does, but somehow he managed to take all the fun out of it.
Sheldon: Once again, it's what I do.

Sheldon: I don't want to tell you how to do your job, but when a mouse completes a maze, it gets a food pellet.
Amy: It also gets its brain plucked out with tweezers.
Sheldon: And its last meal was a food pellet? You're a monster.

Sheldon: I'm so excited. And I just can't hide it.
Leonard: Oh. I'm about to lose control. And I think I like it.
Sheldon: What are you talking about?

Raj: You call yourself a friend? I was trying to help you. And at the first sign of trouble you ran away, leaving me to fend off a family of rats! You're a completely selfish human being and a physical & moral coward.
Sheldon: His statements of the obvious continue to annoy.

Sheldon: Do you want to say it?
Amy: Let's say it together.
Sheldon and Amy: We're getting a turtle!

Sheldon: Sorry, kid, you got it worse than a gibbon.
