The Oct. 20 episode of MythBusters in which Jamie and Adam find out what really happens when “the poop hits the fan” could produce the most cringe-worthy Discovery Channel moment since Bear Grylls gave himself an enema on Man vs. Wild. Below, watch two clips. The first shows the guys scooping a sample from a bucket of dog poop and putting it through tests to determine the specs (like “stickiness”) of the hygienic artificial excrement they’ll create for their big experiment. The second shows Adam determining how one best hurls poop 30 mph at a target with certain levels of accuracy and consistency. I s— you not.
