A Word of Etiquette

I don't want to be overly focused on toilets, commodes, or other latrine-related issues, but I do have two words that I just have to say. I realize that you are all very considerate, conscientious people who don't really need to hear this, but I find myself having to get these two words off my chest. I believe these two words, when put into action, can make the workplace -- nay, the world -- a much better place: courtesy flush.
