Wil Wheaton: So, we finally meet.
Mark Hamill: I'm sorry, who are you?
Wil Wheaton: (scoffs) I'm Wil Wheaton. I was supposed to officiate this wedding. I was up all night preparing these notes.
Mark Hamill: Well, thanks so much. It's gonna be a great help.

Wil Wheaton: Game over, Moonpie.

Wil Wheaton: Did that guy just say "Revenge is a dish best served cold" to me in Klingon?

Wil Wheaton: Hey look, they named their team after me!

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.
