You are in a room. There are four solid walls, solid roof and solid floor. No door, no windows. All there is in the room is you and a plank of wood. The nearest town is 50 miles away.
How do you escape and get to the town?

You rub your hands together until they are sore (saw). You use the saw to cut the plank in half. You put the two halves together to make a whole (hole). You put the hole in the wall. You walk through the hole and shout until you are hoarse (horse). You get on the horse and ride to the town.
