Sheldon: Point of inquiry, why did you put your car key in the door lock?
Penny: Why? I'll tell you why. Because today I had an audition, it took me two hours to get there, I waited an hour for my turn, and before I could even start they told me I looked too Midwest for the part. Too Midwest? What the hell does that even mean?
Sheldon: Well, the American Midwest was mostly settled by Scandinavian and Germanic peoples who, well they have a characteristic facial bone structure...
Penny: I know what it means, Sheldon!
