Leonard: Do you think Penny's mad at me?
Bernadette: Because you're in the right lane behind a bus and you won't go around it? I'm sure she finds it charming.
Leonard: No, because I didn't want her on my team.
Bernadette: I'm starting to think she dodged a bullet. The slowest bullet in the world.

Bernadette: (Shouting from the bathroom) How many times do I have to tell you to replace the toilet paper when it's empty?
Howard: I'm in the middle of something.
Bernadette: So am I!

Bernadette: Gosh, Amy. I'm sensing a little hostility. Is it maybe because like Sheldon's work, your sex life is also theoretical?

Bernadette: You better find my husband's mother, 'cause one way or another we're walking out of this airport with a dead woman.

Amy: As my mom used to say, "When you're doing a puzzle, it's like you've got a thousand friends." She was full of fun lies like that.

Penny: Run to India.

Sheldon: My brain is better than everybody's!
