Research conducted by award-winning U.S. scientist Nathan Zohner concluded that roughly 86 percent of the population supports a ban on dihydrogen monoxide. Although his results are preliminary, Zohner believes people need to pay closer attention to the information presented to them regarding Dihydrogen Monoxide. He adds that if more people knew the truth about DHMO then studies like the one he conducted would not be necessary.

A similar study conducted by U.S. researchers Patrick K. McCluskey and Matthew Kulick also found that nearly 90 percent of the citizens participating in their study were willing to sign a petition to support an outright ban on the use of Dihydrogen Monoxide in the United States.

... which is one hell of a lot more subtle than, but inevitably reminds me of, this:

Unlike traditional water bottling facilities who bottle water only from one specific region, we have designed an innovative blending system that harnesses and compresses the benefits of waters ranging from the French Alps to the Rocky Mountains. Our 27-step process bonds the molecules and rigorously blends the waters together. It then secretes the water molecules and harvests them for the final stage. Once ready, the substance is introduced to the environment and the excess vapors are released. The remaining substance is pure, natural, dehydrated water.
