Possibly – although no one’s admitting anything. The Wall Street Journal traced the video to “a computer registered to DCI Group, a Washington, D.C., public relations and lobbying firm whose clients include oil company Exxon Mobil Corp.”

A DCI Group spokesman declines to say whether or not DCI made the anti-Gore penguin video, or to explain why Toutsmith appeared to be sending email from DCI’s computers. “DCI Group does not disclose the names of its clients, nor do we discuss the work that we do on our clients’ behalf,” says Matt Triaca, who heads DCI’s media relations shop.

Dave Gardner, an Exxon spokesman, confirms that Exxon is a client of DCI. But he says Exxon had no role in creating the “Inconvenient Truth” spoof. “We, like everyone else on the planet, have seen it, but did not fund it, did not approve it, and did not know what its source was,” Mr. Gardner says.
