12. If only a breeder
I worked at a veterinary clinic when I was in high school. One day a vet came out of the exam room and asked me how to tell if a puppy was a girl or a boy. Thinking it was a joke or a trick question, I said, "You turn them over and look, don't you?" The vet sighed and left. Clearly, the doctor asked seriously how you tell if a puppy is a boy or a girl.
