What did people yell when empting a chamber pot?

When emptying a chamber pot, it was common for people to yell "Gardeyloo!" This term was a warning to pedestrians below that waste was about to be thrown from a window, allowing them to move out of the way. The phrase is derived from the French "regardez l'eau," meaning "watch out for the water." It served as a practical alert in the times before proper sanitation systems were established.
