Your kids may come home snickering today and saying, "Today Is Crapper Day!"
Because, supposedly, England's Thomas Crapper invented the flush toilet. But contrary to popular belief, he did not invent it. He improved it in the 1800's and held 9 patents, but he did not invent it. It can be traced back to England in the 300's BC. Over 2400 years ago. I think, back then, the Roman Empire had been ruling and I remember my Dad telling me stories about the all night parties the anciant Romans had. Eat, Drink and everything else to absolute excess. So I would figure that they may have needed flushing toilets and that's what birthed the concept.
