Josh: So, I have to ask, was the robot sexy?
Howard: It was actually just a mechanical hand.
Josh: 'Cause that's all you need, right?
Howard: You are my brother.

Howard: You know, I'm really glad you decided to learn Mandarin.
Sheldon: Why?
Howard: Once you're fluent, you'll have a billion more people to annoy instead of me.

Sheldon: Sheldon Cooper does not cry.
Howard: That's true, you'd rust.

Penny: Howard, cow tipping - real or not?
Howard: I'm going to say not. That's just based on me trying to roll my mom over when she's snoring.

Sheldon: It reminds me of when my stupid brother and sister would build forts in the living room, and wouldn't let me in. I hated that so much.
Amy: You know, there's nothing I can do about getting you invited to the symposium, but if you wanted we could build a fort.
Sheldon: Isn't that a little juvenile?
Amy: More juvenile than this? *Puts up picture of smiling Sheldon to her face*

Leonard: Well, you can spend the rest of the day being bitter about this--
Sheldon: Agreed.
Leonard: I was going to say "or," but why bother?

Howard: Hey, I threw out the first pitch at an Angels game.
Josh: Wow.
Bernadette: He did it with a robot.
Josh: You had sex with a robot?
Howard: That's not what she meant.
Raj: But technically, yes.
