More than an ad for a vehicle, this is really an ad for wasting a gratuitous amount of energy in the name of having a good time. And who doesn't want to burn a bunch of coal fuel in the name of smiles?
Of course, the makers of the ad wanted the Juke to appear to be the entity causing everything to light up in glory, but everyone knows where electricity comes from. Even in this weird fantasy land, coal is being burned by the ton to keep those lights blazing.
By the way, where are all the people? In the end, it's apparent that there were, in fact, people in this world, but their lives were dull and miserable until the Juke came along and started busting out light bulbs. That's when the trendsters come out of the woodwork to enjoy the spectacle.
And what's with the inexplicable cross dresser at the end? Seems he had a rough night, but for some reason a distant flicker of hope beams into his eyes, and he gains the courage to go back out on the town. Thanks, Juke.
