3. Thomas Crapper gets most of the credit for inventing the modern-day flush toilet in

1861. But before that the actual invention of the flush toilet can be traced back to a Brit named Sir John Harrington who, in 1596, devised a mechanism with a cord that, when pulled, flushed away waste with a rush of water.

I guess nobody wanted to say they had to take a Harrington!

I have personally observed this in a tour of the old Aztec Palace
that can be seen at The Zocalo in Mexico City. No shit!
