Leonard: Kripke.
Barry Kripke: What's up, fellas?
Howard: Did you screw us over?
Barry Kripke: Ooh, I can't tell you that. It's classified.

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.

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!

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

Howard: Why would the military want Sheldon?
Leonard: I don't know. Target practice?

Barry Kripke: Whoa, whoa, whoa. You didn't tell me we were doing this just to stick it to Sheldon.
Leonard: Well-
Barry Kripke: I messing with you. This sundae just got a cherry on top!

Sheldon: And worse than that, Edison filmed the first on-screen kiss, so he's basically a pornographer. Although every time I put that in Wikipedia, someone takes it out.
