Two fathers and two sons go fishing. The catch that day isn't good, so they only catch three fish. That happens to be their only supply of food, so they split it evenly, without cutting, slicing, or mauling any of the fish. How is this possible?
Three people go fishing. A grandfather, the grandfather's son, and the grandfather's grandson. The grandfather's son is the father of the grandfather's grandson. Therefore two sons are present and two fathers are present, yet it is possible that only three people be present. Therefore they can have one fish each.
