Two campers are searching an area, one with a flashlight while the other one is searching on the ground.
Another camper walks up and asks the first one what he is doing. He says "I dropped my quarter and now I'm looking for it."
You keep doing this till all your campers have gone except for one.
He says to the first boy "watcha doing?" The first camper says "I dropped my quarter" Then the other camper says "Where did you drop it at?" The first boy says "Over there." (pointing to a different spot.)
The other boy says "Then why are you looking over here?"
The first boy says "Because this is where he is holding the flashlight."
