Penny: Okay, everybody, Sheldon is gonna come back out, but I think he's a little embarrassed, so let's all be extra nice, okay?
Barry Kripke: What are you looking at me for? I'm a saint. (chuckles) But a sinner in the sack.

Barry Kripke: Someone call Animal Control. There's a cougar on the loose.
Beverly Hofstadter: Barry, stop.
Leonard: Seriously, Barry, stop.

Barry Kripke: (Knocking) Hello! Some of us need to check our hair because we might have a shot with Leonard's mother.

Raj: But, Amy, when you and Sheldon split up, didn't you start dating someone right away? Amy: Well, I ... I wouldn't say right away.
Sheldon: And actually, it was three different men.
Barry Kripke: Three different men?! Damn, girl, way to give the milk away!

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.

Leonard: Can you give us a minute?
Barry Kripke: Take your time. I'll walk out backwards for dramatic effect.

Leonard: Hey, Barry, we're in trouble. We need liquid helium. Does the department have any we can use?
Barry Kripke: Sorry, there's a shortage. And what we do have I need for my quantum excitation study.
Sheldon: But you won't need much for that.
Barry Kripke: True, but if it's successful, I'm having a party with balloons.

Sheldon: Why would you do that? You're a string theorist as well.
Barry Kripke: Incorrect. I'm a string pragmatist. I say I'm going to prove something that can not be proved. I apply for grant money and then I spend it on liquor and broads.

Barry Kripke: Excuse me, fellas. Sorry for eavesdropping, but there actually was some big string theory news out of the Hadron Collider.
Sheldon: Really? Did they find evidence to support extra dimensions or super-symmetry?
Barry Kripke: No, but they did find evidence you'll believe anything

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: 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.

Barry Kripke: There he is! It's my favorite superhero, The Retractor.

Barry Kripke: I'd love to babysit for you. Kids love me. Something about me just makes them waff and waff.

Kripke: If you need my nose, you'll find it firmly lodged up the rectum of the tenure committee.

Barry Kripke: Nobody cares, Hofstadter. Wrap it up.
