A middle-aged couple have two gorgeous teenage daughters. They like to have a son and decided to give it one more try.
After a few months the woman is pregnant and nine months later gives birth to a healthy boy.
Her husband rushes to the hospital to see his son.
He is astonished, because besides his wife is the ugliest baby he has ever seen.
He says to her “I cannot possibly be the father of this hideous child, look what a difference there is compared with our beautiful daughters.”
Suddenly he realizes what could have happened and sternly asks his wife:
“You did not go to bed with another man?”
The woman smiles sweetly and replied:
“No darling, not this time.”
