The Int'l Center for Bathroom Etiquette is just the place to go if you were wondering about Talking in the Bathroom, Which Sink to Use, Kiddie Urinals, Which Way to Hang the Toilet Paper, etc. They even have an online training guide. How handy with all the holidays coming up!
There is a forum for you to post all those nagging questions you've had over the years and get them answered. Here is a typical entry:
Q: "What is the best angle of incidence for one to urinate at so as to create the minimum quantity of "splashback"?
A: "Well that's a tough one to answer, since it can often depend a lot on the shape of the urinal itself. I find however that typically it's best to pee more or less pointing downwards, as opposed to straight out. If you pee straight out it will deflect back into your leg, but if you aim the pee down it tends to get trapped in the bottom of the bowl. Maybe we need to run some computer simulations on this one."
They are looking for more women correspondents... Ladies...anyone?
