Penny: No, Fritz, I need you on my flank. No, I don't know German. Flankenzie, flankenzie!

Sheldon: Woman, you are playing with forces beyond your ken.

Raj: [to Amy] If you were having Sheldon's baby, would you really want him in the room?

Sheldon: Level 3 and she thinks she's rich. What a noob!

Leslie: Hello men. Sheldon.
