Howard Wolowitz:
Sheldon knows football?

Leonard Hofstadter:
Apparently.

Howard Wolowitz:
I mean Quidditch, sure. But football?

Leonard Hofstadter:
Sheldon, how do you know this stuff?

Sheldon Cooper:
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.

Leonard Hofstadter:
Unbelievable.

Sheldon Cooper:
If you're interested, I also know all about frying meat that isn't chicken as if it were chicken.

Leonard Hofstadter:
So you could teach me?

Sheldon Cooper:
Football or chicken fried meats?

Leonard Hofstadter:
Football! I'm going to Penny's on Saturday to watch a game with her friends, and I don't want to look like an idiot. I want to blend in.

Sheldon Cooper:
If you want to blend in with Penny's friends, I think looking like an idiot would be the perfect camouflage.
