Leonard: Guys, it's stolen. It should go back to Peter Jackson. He made the movies, it belongs to him.
Howard: Fine. He can have it back as long as he promises to make me a hobbit in his next movie.
Raj: There are no Jewish hobbits.
Howard: Clearly, you've never been to my house for dinner on Rosh Hashanah.

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: One ring to rule them all.
Rajesh: One ring to find them.
Wolowitz: One ring to bring them all.
Leonard: And in the darkness bind them.
Rajesh: Holy crap are we nerdy!

Leonard: What was that?
Penny: Sheldon tried to steal the ring so I punched him.
Leonard: That's my girl!

Sheldon: So, just to clarify, when you say three, do we stand up or do we pee?
