A young man was visiting a friend in Germany, in the northern part of the country, when he took him for a walk in the woods. But in the middle of the wilderness, the friend really wanted to show him two pipes coming out of the ground and looking like two huge periscopes.

It seems that this man’s friend was always playing there, but his parents had warned him never to get too close to them.
