One evening, I went with my parents to a fancy restaurant. Dad was about halfway through his meal when he took a hard look at the potato, called the waitress over and said, "This potato is bad!"

To my utter amazement, the waitress at this "5-Star" place, picked the potato up, smacked it, put it back on the plate, then told my Dad, "If that potato causes any more trouble, just let me know."
