A middle-aged couple had two beautiful daughters but always
talked about having a son. They decided to try one last time for
the son they always wanted. The wife got pregnant and delivered a
healthy baby boy. The joyful father rushed to the nursery to see
his new son. He was horrified at the ugliest child he had ever
seen. He told his wife: "There's no way I can be the father of this
baby. Look at the two beautiful daughters I fathered! Have you been
fooling around behind my back?"
The wife smiled sweetly and replied: "Not this time!"
