Evolution of a toilet

Here's a first: I was doing the weekly Turnip yesterday and came across a bunch of dates so fascinating, I thought they deserved their own post. Via plumbingworld.com, we have highlights of the evolution of the toilet from 2500 BC to 1990 AD. (The dates come from a paper presented by Dr. Bindeswar Pathak, Ph.D., D.Litt. at the International Symposium on Public Toilets held in Hong Kong, in case you're wondering about the Indian-slant, as well as the grammar. Still, you'll be able to impress everyone around the water cooler, me thinks... especially if you click through to the paper and quote the first line: UNLIKE body functions like dance, drama and songs, defecation is considered very lowly.")
