Save the planet. Invade a country.

One of my favorite South Park episodes involved the environmental hazard posed by a massive cloud of "smug" resulting from the decision of all of the town's residents to buy environmentally-friendly hybrid cars.

Well, they needn't have bothered. It seems that there's a much better choice than a hybrid, from an environmental point of view.

It's called a Hummer.

Just think of the contribution to the battle against global warming being made by the war in Iraq!
