Amy: I just hope I did the right thing.
Stuart: I'm sure you did. Maybe that's the problem, you always do the right thing. Maybe it's time to do the wrong thing?
Amy: Like you're doing right now?
Stuart: Exactly.

Stuart: Oh, Sheldon, I'm afraid you couldn't be more wrong.
Sheldon: More wrong? Wrong is an absolute state and not subject to gradation.
Stuart: Of course it is. It's a little wrong to say a tomato is a vegetable, it's very wrong to say it's a suspension bridge.

Howard: Hang on, I know a place where you could you stay and earn some money at the same time.
Stuart: Great!
Howard: I just have to warn you: it will involve humiliation, degradation and verbal abuse.
Stuart: So, what's the catch?

Bernadette: Hey, Stuart.
Stuart: *startled* Hey.
Bernadette: Sorry, did I startle you?
Stuart: Yes, but at this point pretty much any customer does.

Amy: Hold on. You're getting married and you didn't invite me?
Penny: It was kind of a spur of the moment thing.
Amy: Wow. Hope I can catch the bouquet from here.

Leonard: Penny. We are made of particles that have existed since the moment the universe began. I like to think those atoms traveled fourteen billion years through time and space to create us, so that we could be together and make each other whole.

Bernadette: Aww, that was beautiful.
Howard: Yeah. I mean, not like our wedding beautiful.
Bernadette: No, we totally won.
