You should invest in a can of this artist's poop

In 1961 artist Piero Manzoni preserved his excrement in 90 signed cans, each containing 30 grams of his solid waste. The Merda dArtista are becoming more valuable over time.

Via Oddity Central: In 2007, the Tate art gallery in London, bought one of Manzonis 90 cans for 22,350 ($30,000), and while that may seem like a lot for what is literally just canned crap, they actually got a great deal. In 2007, another can of Merda dArtista was auctioned off in Milan, for a whopping 81,000 ($108,000). Crazy, right? Not really, just another good deal, because Manzonis cans of poop are currently worth around $300,000 apiece. Last year, someone bought can no. 54 for 182,500 ($242,000).
