There's a new ad campaign going on in Brazil urging people to pee in the shower. The group behind the campaign claims that if you do pee in the shower and eliminate just one toilet flush a day, it can save 1,100 gallons of water in a year. That's a lot of water to save. If that works, I'm all for it. But I have to put a call in to my many Brazilian friends to explain that if they plan on visiting me, they will now be staying in a hotel.
