Quaid doesn't get jokes.

She just doesn't get them. Even if they're obvious.... the only jokes she seems to understand are when you are criticizing the store manager who has some ridiculous ideas about how to run a store. She doesn't seem to get sarcasm either, and if you were to point out that you were either joking, or being sarcastic, she would treat you like YOU are the moron. Hopefully she'll die in a car crash one day.
