Mrs. Latham: I no longer care, dear. But don't worry, I really enjoyed meeting you this evening.
Leonard: You're kidding. That was good for you? 'cause I was sweating through my T-shirt.
Mrs. Latham: Excellent! There's nothing I like better than making smart people feel ill at ease.
Leonard: Why?
Mrs. Latham: Oh, I don't know, it's one of the fun things you get to do when you have lots of money. Watch. (To Raj) Hey! Who said you could eat that shrimp? See? Fun.

Penny: Good morning, slut!
Leonard: What?
Penny: Oh, please! I recognise the walk of shame when I see it. All you're missing is a little smeared mascara and a purse with panties wadded up in it!

Sheldon: Given how much time you spend engaging in pointless self-abuse, you might consider, just this once, using your genitalia to actually accomplish something.

Sheldon: An entire dinner to talk about your research? Where you going? The drive thru at Jack In The Box?
