Somehow this story didn't quite work for me :|
(It does feature cute illustrations, however)

This is the story of John-Paul, the son of a wealthy factory owner. One night when his father invites some senior executives over for dinner, John-Paul is so bored with all the grownup talk around him, that he decides to add the worms that he uses as fishing bait to the bowls of salads, that had been laid out for dinner.

Perhaps the story is funny in its native language (it's been translated from French), but I just ended up feeling rather sorry for the worms :|
