Rule 34 of the Internet states that if something exists, there's a porn of it. No exceptions. And while this discovery isn't technically porn, it represents the same sexualized can-do attitude that's willed the rule into existence.
UK bondage company Bondara made an Iron Throne out of dildos to coincide with its new "Game of Bones" product line (NSFW link obvi). The project took 200 dildos, 24 hours, and a complete lack of shame to complete. If you want to own the "Rubber Throne" you'll also have to shed any sense of shame and tweet out a link to be entered in the giveaway. Only United Kingdom residents are eligible, however.
That means we have little hope of seeing Snoop Dogg getting high on the Rubber Throne.
