Well, it has always felt good but now it seems that it is doing good, at least according to this new piece from Saatchi & Saatchi Brazil for SOS Mata Atlântica. The group is of the Atlantic rain forest-saving variety (see this recent cutting-edge piece with a stunning reveal and this smart Google Maps demonstration). In the spot, animals, aliens, and famous apes relieve themselves during showers and the spot finishes by stating the importance of saving 12 litres (Hispanic for 'liters') of water.
While there may be other issues with pissing down your tub's drain, the work utilizes such a lighthearted and carefree tone that, no matter how gross women think it is, it's great for Miss Nature and her bushes. Or, if you've got some Febreeze, take a less philanthropic approach.
