A couple has 4 kids. Three of the kids were very pretty and the fourth one is no where near the first three so the husband was suspcious that maybe the fourth one was not his and that yhe wife must have an affair with another man. He tried to restrain himself to ask his wife about it but then one day he could not resist and approached his wife and he said "Darling look at our fourth child, looks very different from the 3, who is really the father? The wife replied " the truth of the matter is the fourth one is yours!
