The answer ...

"Whenever folks who have lived or traveled in Germany/Holland gather for a beer, sooner or later one subject is sure to rear its ugly head: what is the deal with those toilets?"

German/dutch toilets are quite extraordinary. Other European toilets - well, the ones that aren't merely holes in the floor - work much like their North American cousins. They are shaped a little differently, but the basic principle is the same: the excrement either lands directly in the water or it slides down a steep slope into the water, before being flushed away. Simple, effective and clean. Not so the German toilet. The excrement lands on a bone-dry horizontal shelf, mere inches beneath one's posterior. Repeated flushings are required to slide the ordure off the shelf into a small water-filled hole, from which it hopefully disappears. See the pic?

I do not understand the purpose of this toilet. It does not save water - you must flush it eight or ten times to remove every last scrape and smear. It is not hygienic - the smell is ungodly. The only conceivable explanation is that Germans love to inspect their stool, so the German toilet of necessity features a built-in stool inspection shelf. I wouldn't be surprised if the more expensive models include a digital scale: "Mein Gott, zwei kilogram!" exclaims Günter, joyful and relieved.

Further research has revealed that the German toilet is in fact designed to facilitate stool examination. This is a wise, healthy practice, argue Germans, a person's best defence against intestinal disease, water-borne parasites or worm-riddled, undercooked pork sausage. While this made perfectly good sense around 1900, thanks to improvements in public health the whole shelf business should have become obsolete shortly after World War II.
