Mark Hamill: We're here to celebrate the marriage of Sheldon Lee Cooper and Amy Farrah Fowler. I had more prepared, but I'm just gonna skip to the rings and vows, since I've been answering your questions for 45 minutes.
Stuart: Yeah, he answered 'em.

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: So are you feeling okay? No wedding jitters?
Sheldon: No. There is nothing in the world that would stop me from marrying you tomorrow, even me from the future coming back to prevent the wedding and the subsequent birth of a child who will destroy humanity.
Amy: Because if you came from the future, that would mean you already went through with the wedding because you believe that time travel is on a closed loop.
Sheldon: I love you so damn much.

Sheldon: Amy, I usually know exactly what to say. But in this moment I have no words.
I guess I'm overwhelmed by you. In a good way. Not in the elevator in the Haunted Mansion way. Even if I can't tell you now how I feel, I will spend my life showing you how much I love you.

Sheldon: Are you having an allergic reaction to my boutonniere?
Leonard: No. I'm just so happy for you. And for me. After today, you are officially - and, more important, legally - Amy's problem.
Sheldon: Don't be silly, Leonard. I will always be your problem.
