Bernadette: The thing is, my mother worked full-time. I had to take care of my brothers and sisters.
Howard: Yeah, so?
Bernadette: Ugh, it was horrible. With their snotty noses and their poopy diapers and their little shrieky voices, always complaining. I don't want to get dressed. Joey keeps spitting in my mouth. This isn't the way Mom makes waffles. Well, okay, put your hand in here. Let's see how you like this waffle!

Bernadette: She's just being nice.
Howard: Well, I'm her son, how come she doesn't send someone to check on me if I'm lonely.
Bernadette: Because you have a wife!
Howard: Yeah, well, sometimes you work late.

Howard: My arm is feeling numb. *Howard rubs his right arm*
Bernadette: That's the wrong arm for a heart-attack, doofus.
*Howard switches to his left arm*

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: Jewelry? Seriously? Sheldon, you are the most shallow, self-centered person I have ever met! Do you really think another transparently manipulative - Oh, it's a tiara! Put it on me, put it on me, put it on me, put it on me.

Penny: You look beautiful.
Amy: Of course I do, I'm a princess and this is my tiara!

Sheldon: Hard as this may be to believe, it's possible that I'm not boyfriend material.
Leonard: Glad I was sitting down for that.
