Raj Koothrappali
- Leonard Hofstadter: [Looking at their invention journal] Boy, I haven't looked at these in years. Let's see... robot girlfriend...
- Howard Wolowitz: That was mine.
- Leonard Hofstadter: Robot prostitute...
- Howard Wolowitz: Also mine.
- Sheldon Cooper: I'm confused. Why would you have both a robot girlfriend and a robot prostitute?
- Howard Wolowitz: There are some things you don't do with your robot girlfriend.
- Raj Koothrappali: Boy, when Howard married Bernadette, the field of robotics really took a hit.
- Howard Wolowitz: Can't argue with him, it's right there on the screen. Austria really does look like a wiener.
- Raj Koothrappali: Forget that, check out how hung Florida is.
- Leonard Hofstadter: I'm sure Mrs. Florida walks funny. Can we get back to work?
- Howard Wolowitz: My cousin has a cabin out in the woods.
- Sheldon Cooper: I'm not going to a cabin in the woods. Did you see the movie Cabin in the Woods?
- Leonard Hofstadter: Then we'll go to a hotel.
- Sheldon Cooper: A hotel? Did you see The Shining?
- Raj Koothrappali: We could go up to Big Bear and get a house on the lake.
- Sheldon Cooper: Did you see The Lake House?
- Raj Koothrappali: Nothing bad happens in The Lake House.
- Sheldon Cooper: Yeah, well, no, not to them. To me. Time traveling mailbox. The only time that traveled was an hour and half of my life down the toilet!
- Raj Koothrappali: Hey, I read that someone invented a way to convert your footsteps into electromagnetic energy so you can charge your cell phone while walking.
- Leonard Hofstadter: We had that idea years ago. How come we never did anything with it?
- Howard Wolowitz: Probably because we left the diagram of it in the restaurant, and none of us wanted to walk back.
- Sheldon Cooper: I know the real reason you never made progress with that idea. You thought of it September 22, 2007. Two days later, Penny moved in, and so much blood rushed to your genitals, your brain became a ghost town.
- Leonard Hofstadter: Negative reinforcement isn't working.
- Sheldon Cooper: I think you mean positive punishment. Negative reinforcement is the removal of a positive stimulus. It's a common mistake.
- Howard Wolowitz: Negative reinforcement is really wrong?
- Sheldon Cooper: Oh, it's used incorrectly all the time. Even Bill Murray makes that mistake in the first scene of Ghostbusters.
- Raj Koothrappali: No way. Not Bill Murray!
