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: 'No, not this time!'
