Questions That Leave You Stumped

I work at an organic wood-fired pizza restaurant.

Customer: “So, how are the pizzas baked?”

Me: “In our firewood oven.”

Customer: “Is the firewood all natural?”

Me: “As opposed to…?”

Customer: “Fake!”

Me: “The wood we use to heat the ovens is not fake, sir.”

Customer: “Hmm… well, it better be! I can taste it when fake wood has been used!”
