"Did That Voice Come From The Box?"

I was walking down the street when I saw a small wooden box by the road. Suddenly, I heard a voice say,"Help! Let me out of here!" To my surprise the, voice was coming from the box.

If this was to really happen to me I would just walk pass the box. I would do this because I feel it would be a set up. Another thing I would do is, I would kick the box over to see what comes out. If something comes out I would see what it is first, then decide my actions. If it is a set up I would run and never go back to that spot again.
