A rich man has two sons. When he dies, the sons read his will. The will says
the sons must race their horses to a distant city and the LAST one's horse to
get there gets the fortune. So the sons start racing as slow as possible to
get the fortune. At nightfall they stop at an inn. They tell their problem to
the innkeeper and in the morning the sons are racing as fast as they can to
the city. What did the innkeeper tell them to do?
He told them to switch horses. So if one son gets there first, he will be on
his brother's horse and his horse will be last and he will get the fortune.
