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.

Amy: Okay, what is going on?
Penny: We just want you to be prepared for any surprises that could happen tomorrow.
Amy: What surprises?
Bernadette: We don't want to spoil anything, but you should know that Sheldon said he's ready to be physical.
Amy: You shut your damn mouth! You actually heard him say this?
Penny: Yes, he said he wants to do something to show you how much you mean to him.
Amy: I can't believe it. I don't know what to say.
Bernadette: Well, we're really happy for you and we know how much-
Amy: I do know what to say. Let's get me waxed!

Amy: I guess it must have been back when I was in the Girl Sprouts.
Bernadette: Girl Sprouts?
Amy: My mom made it up as an alternative to the Girl Scouts. She didn't want me selling cookies on some street corner like a whore.

Sheldon: Sheldon Cooper does not get lucky.
Amy: You and me both, brother.

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.

Mark Hamill: Welcome. We are gathered here today in the sight of family, friends and Almighty God.
Sheldon: That's too religious.
Mark Hamill: That lady over there made me say it.
Mary: He heard you, and he can't un-hear you.

Barry Kripke: At wast, my wove has come awong, my wonewy days are over, and wife is wike a song, oh, yeah.
