Well known culture jammers, the Yes Men,  who practice what they call 'identity correction' by posing as representatives of well-known corporations and organizations and making outrageous comments on their behalf, pulled off their latest installation of genius at the Oil and Gas Exposition 2007 in Calgary.
Posing as members  of the National Petroleum Council, they unveiled Vivoleum, an oil product derived from dead victims of global warming disasters.
Participants at the luncheon, of which the Yes Men were the keynote speakers, participated in a ceremonial lighting of Vivoleum candles until organizers began to catch on and eventually had them escorted out of the building. For more on Vivoleum check out their Vivoleum specific website and for Alberta coverage on the event see this Calgary Herald article.
We don't have any video from the event yet, but here's a photo slideshow we found on Flickr. 
And below is a a Vivoleum spoof video we found on Youtube, a tribute to "Reggie" the first human who volunteered to have his body turned into fuel.
