Barry Kripke: Cooper, maybe physics just isn't your thing. Have you ever considered a career in retail? Then you could take things back for a living.

Amy: Hi. You're on Fun with Flags.
Barry Kripke: Hello. I want to talk about how lonely I am, too.
Raj: Kripke? Is that you?
Barry Kripke: Yeah, I'm just sitting here all by myself wondering if I'll ever find someone to share my life with. Preferably Asian, 18-24, no fatties.

Barry Kripke: Yes, yes, yes. He's a jolly good fellow. What time do the strippers arrive?

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!

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.
