Amy: Sheldon, you said you were unhappy getting attention for something you wish you never did.
Wil Wheaton: Yeah, I know a little something about that.
Sheldon: Nonsense, Wil. Your endless tweets are not that bad.
Wil Wheaton: I remember why it's been a while.

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!

Bernadette: Aww, Raj did the dishes.
Howard: How do you know I didn't do them?
Bernadette: Because once when all the knives were dirty, you cut a bagel with your keys.

Sheldon: No, that's okay. I can fight my own battles. Isn't that right, Bawwy?
Barry Kripke: Is that a reference to my speech impediment? That's pretty hurtful. I can't control it.
Sheldon: You're right. That was uncalled for. I take it back.
Barry Kripke: Of course you do, because you're The Retractor!

Penny: (To Raj's dog) Bark once if you need me to call PETA.
