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: Aww, Raj did the dishes.
Howard: How do you know I didn't do them?
Bernadette: Because once when all the knives were dirty, you cut a bagel with your keys.

Penny: Run to India.

Sheldon: My brain is better than everybody's!
