...in Munich we lived in a basement suite where the water pressure was too high. Worse, the shelf was actually slightly concave, forming a shallow bowl. The first time I flushed the toilet the water came rushing through so forcefully that a small chunk of poo launched off the lip and shot out over the floor. After that we always held the lid down when we flushed. I swore you could feel a kick as the turd ricoched off the underside.
