SARCASM: Isn't One of the Commandments "Thou Shalt Not Be Stupid?"

On a recent episode of the TV quiz show Cash Cab: After Dark I heard the following:

The question was regarding one of the Ten Commandments. The two people playing the quiz were a twenty-something male and female.

The female hears the question and looks at her partner and says, "Hellooooo, I'm Jewish, I don't know the Ten Commandments."

Um, what?

Did she get hit in the head with one of the tablets that Moses brought down from the mountain and presented to...THE JEWS!?!

Oy vey! It's called the Old Testament, people. LOL!
