Shit artist.
A work of art by the Italian artist Piero Mandzoni, a representative of conceptualism.
In May 1961 Manzoni gathered his feces in 90 numbered banks, each containing 30 grams, he wrote "100% natural shit of the artist" in Italian, English, French and German and sold them at a price equal to the price of gold the same weight . The current price is about 30,500 euros. On May 23, 2007, one of the copies was sold for 124,000 euros at the Sotheby's auction.
He had a good formula, I guess.
(I think the tag 'art' would have been appropriate)
