A last Hummer rant

Because I know we all know, and I don't really need to go on and on and on ...

But really. What is the thinking behind this ad? A quick descrip: two guys in line at the grocery checkout. The guy buying veggies and tofu notices that the guy behind him has huge stacks of raw meat. So he runs out and buys a Hummer. Tagline: "Restore the balance."

Who, exactly, is this supposed to appeal to? Hypocritical vegetarians? Meat-eaters who fear they'll be mistaken for health nuts? People with high blood pressure and low self-esteem?
