Did you ever hear of the channel S.V. Seeker? Honestly my favourite bit of niche internet drama, I can't even begin to list the crazy shit that went down but basically a madman with zero knowledge of sailing let alone boatbuilding welded together an ill-conceived hulk roughly according to the plans of someone who is himself a nutter; misadventures on the way include pouring a lead keel and poisoning the topsoil if not himself, faking an explosion and resulting traumatic brain injury to learn who his 'real fans' were, and creating possibly the scariest boat I've ever heard of which no doubt will end up on the news one day having becoming a hazard to navigation.

Anyway he's the first person I ever heard of using a poo knife. He was openly advocating the practice, as well as a 'poo nest' to prevent splashback.
