Engarde!

I am not used to ranting in my blog. I hope no one suffered heart failure. Perhaps I should establish a warning system.

More interesting, however, is the possibility that loo was a shortening of gardy loo, a warning maids and housewives yelled when they emptied chamber pots out of the window into the street; gardy loo being a corruption of French gardez l'eau ("watch out for water"). Remember, it was Shakespeare's time, and indoor toilets were for the very rich and flush toilets were still a long time away. (Source)

That does sound fun: Gardy Loo! More crap coming!
