Sheldon: They're going to start making Professor Proton's science show again.
Bernadette: I thought he passed away.
Howard: He did. He was cremated, and his remains were put in a baking soda volcano.

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: Until next week, this is Professor Proton saying, 01000010 01111001 01100101. That's "Bye" in ASCII binary, or good-binary.

Sheldon: Well, it should be a scientist I respect. You know, someone with a pleasing voice and symmetrical facial features.
Bernadette: Is he talking about himself?
Penny: If he's talking, he's talking about himself.

Amy: Well, what was wrong with it? You know, did you find it borderline psychotic? I mean, I liked that about it, but you guys discuss.
