The flatus of the Toyota Prius is less harmful than the flatus of a sheep. Who knew? Apparently, Toyota's Israeli arm, that's who.
As you can see from the advertisement above, the methane gas produced by livestock can indeed be worse for the environment (animal gas, including that from humans, is in fact a greenhouse gas) than the emissions from the ass end of an automobile, depending on what you're trying to define – and that goes for any automobile, not just one that's as popular in squeaky clean circles as the Prius hybrid.
We think this is a pretty funny and effective ad, though something tells us it would never see the light of day in the United States. Sadly.
