The Great Amazon Heist, a special premiering tonight on Channel 4 in the United Kingdom, opens on the side of a road, outside of an Amazon fulfillment center in Los Angeles. Oobah Butler, host of Catfish UK and veteran prankster of the Nathan Fielder variety, is pointing at a water bottle full of yellow liquid.

“That’s a bottle of piss!” he shouts, only to do the same again and again in quick succession. In two minutes of scouting the roadside, he collects seven bottles of piss — he suspects one may be apple juice, but upon taking off the lid and sniffing it, he concludes that it, too, is piss.

Such is the start of a journey that takes the viewer through Amazon’s operations. In the course of the one-hour special, Butler works at a fulfillment center, sells a drink made of Amazon drivers’ pee on the company’s platform, has his very young nieces buy knives and rat poison through Alexa, and executes a complex scheme involving filling potholes around London with filler purchased on Amazon before then getting refunded for said filler by returning the packages loaded with sand.
