Sheldon: Woman, you are playing with forces beyond your ken.
Penny: Yeah, well your Ken can kiss my Barbie.

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

Amy: Bernadette, I want to thank you for allowing me to be your maid of honor. I also want you to know that I will be happy to do it again if this marriage craps out.

Sheldon: Would you like some aloe vera? 'cause you just got burned.

Amy: Stop it! Today is not about you, it's about Howard and Bernadette, and me!
