Big Bang Theory Quote
Sheldon: I like the hamburgers where we usually have hamburgers, you can't make the assumption that I'll like the hamburgers here.
Leonard: I'm sorry. Give him a hamburger.
Penny: Uh, which one, the Classic Burger, the Ranch House Burger, the Barbecue Burger or the Kobe burger?
Sheldon: Can't we just go to Big Boy? They only have one burger. The Big Boy.
Penny: The Barbecue Burger is like the Big Boy.
Sheldon: Excuse me, in a world that already includes a Big Boy, why would I settle for something like a Big Boy?
Penny: Because you are not at Big Boy!
Sheldon: Fine, I'll have the Barbecue Burger.
