Sheldon: Thank you, Penny.
Penny: No problem. So, Leonard, I think it's interesting you didn't call your girlfriend to come get you.
Leonard: Uh, I kind of told her I was working.
Penny: So you lied to her. Also interesting.
Leonard: Yeah, she doesn't really understand the whole Warcraft adventure-role-playing thing.
Penny: Well, doesn't matter if she gets it, as long as she's pretty.
Howard: This one's funny, Leonard. How come you couldn't make it work with her?

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.

Bernadette: Maybe we should get one of those machines to help her up the stairs.
Howard: You mean a forklift?

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

Penny: Give my friend his stuff back.
Tod Zarnecki: I don't know what you're talking about.
Penny: Well then good news. Today's the day a girl's finally going to touch you in your little special place. *Kicks him in the groin*

Raj: Come on, dude, bros before ... my sister.

Sheldon: I've never said these words before, but good job, Howard.
