Amy: Wait, are you saying if we combine my experiment with your calculations, we can determine the precise moment in time when the wave function collapses?
Sheldon: It could be the most inspired combination since I mixed red Icee into my blue Icee. It was like drinking 2/7 of the rainbow.
Amy: Sheldon, this is really interesting.
Sheldon: Yeah and this one won't stain my teeth purple.

Sheldon: Gentlemen, the most interesting thing just happened with this spoon.
Howard: Unless it was singing "Be Our Guest," I doubt it.

Sheldon: I spoke with Leonard's mother, and she made me feel better.
Leonard: I don't know who you talked to, but that wasn't my mother.

Hey look at that. You've got a Raj, we've got a Stuart, maybe we should take them to the park and let them run around together.

Howard

Penny: It's like that science thing. For every action you have a gigantic and annoying reaction.
Leonard: Just when I thought you couldn't get any hotter...

Sheldon: Well, I think it's very nice that you're helping out our friend.
Leonard: I think it's nice that you're taking whatever medication Amy is clearly giving you.

That would be amazing. I was literally just looking at my moving boxes trying to figure out which one to live in.

Raj

If you like meatloaf, I'm sure you'll like its cousin, bowl of meat.

Howard

So they're both trying to make each other happy, and the end result is that they make each other sad? That's hilarious.

Sheldon

Oh, Double Stuffed Oreos. I remember when I could afford you.

Raj

Leonard: I don't want to take my shirt off at Comic-Con.
Sheldon: If I may speak for Comic-Con, we don't want that either.

If you don't know how to make lasagna, Google does.

TBBT Quotes

Stephen Hawking: You made an arithmetic mistake on page two. It was quite a boner.
Sheldon: No, no ... that can't be right. I-I don't make arithmetic mistakes.
Stephen Hawking: Are you saying I do?
Sheldon: Oh, no, no, no, of course not. It's just, I was thinking.... Oh, gosh, golly, I made a boo-boo and I gave it to Stephen Hawking.

Sheldon: Why do you have the Chinese character for "soup" tattooed on your right buttock?
Penny: It's not "soup," it's "courage."
Sheldon: No it isn't. But I suppose it does take courage to demonstrate that kind of commitment to soup.
Penny: How'd you see it? You said you wouldn't look.
Sheldon: Sorry. As I told you, the hero always peeks.
