There was a middle-age couple that had two stunningly beautiful teenage daughters. The couple decided to try one last time for the son they always wanted. After several months the wife became pregnant and, sure enough, delivered a healthy baby boy nine months later. The joyful father rushed to the nursery to see his new son. He took one look and was horrified to find the ugliest child he had ever seen.
He went to his wife and said that there was no way that he could be the father of the child. “Look at the two beautiful daughters, I fathered,” he cried. Then he gave her a stern look and asked, “Have you been fooling around on me?”
The wife smiled sweetly and said, “Not this time.”
