Saturday's series of Live Earth concerts—billed as a green event, but really just an elaborate excuse for Al Gore and his all-dad garage band to clumsily perform their one song, a cover of "Smoke on the Water," in front of a global audience—offered up for inspiration some ads featuring the eco-friendly daily habits of Hollywood A-listers.
