This new Mercedes Web ad starring Lara Stone and directed by Alex Prager raises a number of questions. Why are all Stone's facial expressions in the vein of "Ouch! I have, or am afraid of getting, something in my eye"? Why does it make being picked up by a tornado look like a gentle ride in a hot-air balloon? Why didn't a stylist clean the dirt kebab off her stiletto heel before she was lifted skyward? Why are the pieces of flying debris not puncturing her body at high velocity? And if the tornado is strong enough to lift her up, why can't it even budge the car? Who travels with a hatbox nowadays? Where is Lara going, and however will she get back to the automobile of which she seems so fond? [YouTube]
