The mtvU episode in which Cameron Diaz and William McDonough surprised Stanford’s “Maintaining Sustainable Building Projects” class is now available (though you need the dread IE to watch it).

Sadly, the class didn’t seem too interested in Professor McDonough’s lecture on cradle-to-cradle design until Cameron appeared. As Ms. Diaz said, “sustainability isn’t sexy … which is why I am here.” (Ok, the second part was my addition.)
