Got Funny

There was a middle-aged couple who had two stunningly
 beautiful teenage daughters.  They decided to try one last
 time for the son they always wanted.

 After months of trying, the Wife became pregnant and sure
 enough, nine months later delivered a healthy baby boy. The
 joyful father rushed to the nursery to see his new son.  He
 took one look and was horrified to see 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 that child.

 ”Look at the two beautiful daughters I fathered.” Then he
 gave her a stern look and asked, “Have you been fooling
 around on me?”  The wife just smiled sweetly and said, “Not
 this time.”
