Raj: I have a hip-hop aerobics class at five, could we go after?
Sheldon: Sure.
Howard: Also, tonight's the Sabbath and my mother and I have a tradition of lighting the candles and watching Wheel of Fortune, so If we could leave at eight, we'd still be able to regain our birthright at ten, ten thirty latest.

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.
