A middle-aged couple had two beautiful teenage 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 excited father rushed to the hospital to see his new son.

When he got there he was horrified at the sight of the ugliest baby boy 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!'
