Surplus shit perfume
According to website Oddity Central, Jammie Nicholson, a British artist, used his own faeces as the main ingredient for a perfume he calls... Surplus. Each bottle goes for a whopping $65 and best of all, he's already sold 25 of them (probably to Germans).

As the website explains:

Asked about the actual production process of his faeces perfume, Jammie says it all happened in his flat, where he worked with all the windows open and using nose plugs. It took him only a week to extract the "essential oils" from the excrements, then spent a lot longer setting up his distillation device and mixing the crazy concoction.

Reportedly, those who have used it, say it smells pretty good.
