The guy leaves town and entrusts his roommate with his pet fish and potted plant. Flash forward a week and things are bleak: the fish is dead, the plant's decaying, the room's a mess and the roommates just knocked over the urn on the mantle. But no worries: just sprinkle a little Doritos on the problem and all is solved. By the time the roommate is hugging his resurrected granddad, the ad has won us over with its sheer preposterousness.
