Raj: What do you want to do?
Howard: I don't know. I... I'd just like him to go away. I can't deal with this.
Raj: All right, I've got your back.
Howard: Thank you. Come on. And I'd like to point out this wall just provided a lot of privacy!

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.

Howard: I invented a game. Want to play?
Leonard: Sure.
Howard: It's called Emily or Cinnamon. I give you actual quotes I've heard Raj say, and you guess if he was talking to his girlfriend or his dog.

Bernadette: Does your mother call you every day at work to see if you had a healthy lunch?
Howard: My mother calls me every day at work to see if I had a healthy bowel movement.

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*

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.

Leonard: Hang on, if you're making all this money, where is it?
Penny: In a safe place.
Leonard: What does that mean, under your bed?
Penny: No, it means a diversified portfolio of stocks and bonds. I'm not overly conservative. I'm young, so my guy said I can afford to take some risks.
Leonard: Wait a minute, you have "a guy"?
Penny: Don't you have a guy?
Leonard: Why would I have a guy?! I don't have any money!
