Do this one at night around the campfire or be sure to explain to the audience that it takes place at night.
First boy searches the ground around the campfire.
Second boy: “What are you looking for; maybe I can help you find it.
First boy: “I dropped my favorite marble.”
Second boy: “Where were you standing when you dropped it?”
First boy: “Over there.” (He points into the darkness.)
Second boy: “Then why are you looking over there.”
First boy: “Are you kidding? It’s too dark over there. You can’t see a thing.”
