Three blonde women stand in front of a wide river and think of how they
   could get to the other side. Suddenly a ghost appears to them and says
   each of them has one wish.
   
   So the first one says, "I wanna be a hundred times as smart as I am now."   
   
   Then she cuts a tree and rows over the river.
   
   The second looks at that and says, "I wanna be one thousand times as
   smart as I am now."  Then suddenly she jumps to the next group of trees,
   cuts them all and builds a boat.  Then she sails over the river.
   
   The third one says, "Fine. I wanna be a million times as smart as I am
   now."  She looks up, sees the bridge, and walks to the other side.
