I have another one. There are two knights vying for the hand of a princess. Although she would be happy to marry either one, her father on the other hand doesnt want to let her go. So he suggests that they have a horserace with one twist. The one whose horse is last wins the princess' hand. Now at this point the two suitors dont want to start the race they just stay put and it looks like the king wont have to give away his daughter. WHereupon the princess comes over to the knights and whispers something in their ears. THey do something and the race is on. What did she tell them to do?
