A German artist has written to the country's zoos to ask if they would feed his body to the piranhas once he's dead.
Karl Friedrich Lentze, 56, said he came up with the idea after reading about a Dutch man who wanted to be fed to snails.
Lentze, from Berlin, said he liked the idea but wanted something that would gobble him up a lot quicker.
Cologne Zoo is one of those he has contacted, justifying the appeal by saying it could have educational purposes if, for example, it was done in front of a group of biology students.
But zoo director Günther Nogge said even if he agreed it would probably not work.
He said: "It's a great idea. But if you want to carry it out for educational purposes then it would be better if you were fed to the piranhas alive, they're not as keen on dead flesh and prefer their food live."
The artist is however still hoping to hear from other zoos that may be more open to his proposal.
He said: "They could always poke my body with sticks to get me moving and get the fish interested."
Hey, why wait, throw him in there now?
