the schaengel (little john) is a symbol of koblenz. since koblenz was conquered so many times in it's history there were many children fathered by invading troops. the male offspring of these relationships were called "little johns". this statue represents the people of koblenz's disregard of foreign authority. see my warning and dangers tip on a amusing story about this statue.
Das Schängelchen -- or "The Spitting Boy" is the name of a fountain near the City Hall (Rathaus). When we first approached, we noticed the ground was wet in front of him, but we weren't sure why. Soon a few other tourists approached... as they snapped a photo, the fountain decided to spit -- right on them. We had a good chuckle then wisely avoided his periodic spraying.
