Raj: We're not laughing at you. We're laughing with you.
Sheldon: But I'm not laughing.

Penny: Trick or treat.

Penny: Yeah, I am. I'm a pharmaceutical sales rep.

Bernadette: Now, if you'll excuse me, the prime minister of England needs her diaper changed!

Anu: Yep. He interprets me. And guess what's underneath this?... The Bill of Tights.

Leonard: Are you agreeing just to shut me up?
Penny: You got another way? I'm all ears.
