3 women

3 women were hiking when they reached the bottom of a hill. They looked at the map and they realised their destination was on the other side of the hill. They started arguing which was the quicker way to reach their destination, going over or around the hill. In the midst of their argument they find a lamp on the ground and on rubbing it a genie appears and grants then each a wish.
The first woman asked to be 25% smarter and then she goes around the hill.
The second woman asks to be 50% smarter and then she decides to go over the hill.
The third woman asks to be 100% smarter, so the genie turns her into a man and she simply takes the train through the tunnel in the hill.
