Howard: As a scientist you believe the way to understand the universe is through facts and evidence. And now you're counting on some blue chick with a hundred arms to help you?
Raj: That is so offensive. Does everything you know about Hinduism come from Indiana Jones?
Howard: No, there's also Apu from The Simpsons.

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.

Bernadette: Are you okay?
Raj: No, I'm not okay. I feel like I'm going to jump out of my skin.
Bernadette: I told you not to wax down there. It's itchy when it grows back.

Penny: Do I really force you to do things you don't want to?
Amy: Yeah, but it's okay.
Penny: How is it okay?
Amy: I promised myself if I ever got friends I'd do whatever they said. Really, I'm lucky you found me before a cult did.

Penny: Ooh, we could go horseback riding.
Amy: I actually can't. My hips don't open wider than 22 degrees. I rode a very thin pony once. On the first bump I just popped right off.
