I guess it's a measure of the funhouse-mirror strangeness of Peak Oil when Kenneth Deffeyes has to explain that stating "In 2025, we're going to be back in Stone Age" was a joke.

As a token of apology for causing a run on orange-and-black fur tunics, he offers a link to this fascinating ExxonMobil ad which ran on the Op-Ed page of the New York Times and tells consumers, "There's plenty of oil! Don't panic and do something stupid like explore alternative energy. But, um, we need some tax breaks from the government. And hey, don't use too much of it, OK? Just in case. Thanks!"
