Henry and Mary

Henry and Mary had just got married, and everybody was enjoying their wedding party. There was plenty to eat and plenty to drink, and everybody was getting very merry, when a very thin, very young man came into the room. He looked at Mary sadly and accusingly, walked slowly towards her, kissed her lovingly and said, 'Why did you do it?'
    Then he walked to the door and disappeared.
    Nobody had ever seen the young man before--not even Mary.
