Bullshit sandwiches are delicious.

The Wall Street Journal calls the Competitive Enterprise Institute "the best environmental think tank in the country," which should be enough to tell you that "environmental" and "think" are being used ironically. If you need more evidence, Kevin Drum notes their recent ads on environmental carbon dioxide.

The ads, "airing in 14 U.S. cities from May 18 to May 28, 2006," don't merely say that global warming isn't a big deal — though they say that too — they seriously say that carbon dioxide is great stuff. "We breathe it out, plants breathe it in."

Well, there's no arguing with that, especially when it's accompanied by pictures of old growth forests and sweet little girls using their CO2-enhanced breath to blow on dandelions.

Stay tuned for their next ad campaign: "Stop complaining, New Orleans. We couldn't live without water."
