Get naked and cuddle to save energy

That's the message of this so-bad-it's-good PSA parody of March of the Penguins, which substitutes naked people for the birds. The message the UK's Environmental Agency wants you to get out of it: do the green thing by turning down the thermostat and relying on body heat instead.

Folks in the U.S. should watch this ad with particular interest, because trust me--you'll never see the like from the Department of Energy.
