He reported that, while riding a bus in New York City, he observed a mother with eight small children embark. She asked the driver the amount of the fare; he told her that the cost was thirty-five cents, but that children under the age of five could ride for free. When the woman deposited only thirty-five cents into the payment slot, the driver was incredulous. "Do you mean to tell me that all your children are under five years old?" The woman explained that she had four sets of twins. The driver replied, "Do you always have twins?" "No," said the woman, "most of the time we don't have any."
