Penny: Oh, gee, sounds amazing, but, um, I've got some friends coming over. Not a big thing, we're just gonna watch the Nebraska game.
Leonard: Oh. Football, sure.
Howard: Good guess.

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.

Leonard: I think I'm starting to get this.
Rajesh: Really? The only thing I've learnt in the last 2 hours is that American men drink a lot of beer, pee too often and have trouble getting erections.
Leonard: Focus on the game, not the commercials Raj.

Howard: Sheldon knows football? I mean Quidditch, sure, but football?

Sheldon: I grew up in Texas. Football is ubiquitous in Texas. Pro football, college football, high school football, pee wee football - in fact, every form of football except the original, European football, which most Texans believe to be a commie plot.
