McDonald's 'no fry left behind' by DDB Chicago

The ad shows two guys driving along with the passenger snacking on McDonald's fries. One falls into a gap between the two seats and we are then transported into the world beneath the car where a population of people toil and slave in the murky, dust-ridden environment below the surface.

Their exclamations and relief at having been given this fry quickly turn to shocked gasps and outrage as a hand plucks the fry out of its escape hatch and returns it to the passenger in the car.

The guy then says: "There's no one who wants this more than me."
