Check out this pearl from commenter David Ahlport (found in the comments of David Roberts’ Cost Tic post).

I’m a proponent of using ads to spread ideas. The problem with most ads is that they are at best half-truths. This one has it all. They draw a gentle and humorous line between themselves and negative stereotypes. Going green should not be about sacrifice and depravation deprivation. I have seen a few versions of this while channel surfing. We could use a lot more like it.
