Water, Water Everywhere ... which makes it so damned funny

From Wikipedia:

Hellbrunn Castle (German: Schloss Hellbrunn) is an early Baroque castle, or palace, near Morzg, a southern district of the city of Salzburg, Austria, built in the early seventeenth century by Markus Sittikus von Hohenems, Prince-Archbishop of Salzburg. It was only meant for use as a day residence in summer, and the Archbishop usually returned to Salzburg in the evening. Therefore, there is no bedroom in Hellbrunn.

The castle is also famous for its watergames in the grounds which are a popular tourist attraction in the summer months. These games were conceived by Markus Sittikus, a man with a keen sense of humour, as a series of practical jokes to be performed on guests. Notable features include stone seats around a stone dining table through which a water conduit sprays water into the seat of the guests when the mechanism is activated. However, one seat lacks a conduit: that of the Archbishop. Other features are a mechanical, water-operated and music playing theatre built in 1750 showing various professions at work, a grotto and a crown being pushed up and down by a jet of water, symbolizing the rise and fall of power. It should be noted that at all of these games there is always a spot which is never wet: that where the Archbishop stood or sat, which is today occupied by the tour guide.
