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.

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.

Penny: Give my friend his stuff back.
Tod Zarnecki: I don't know what you're talking about.

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

Todd Zarnecki: Who is it?
Sheldon: Your doom.
