Norwegian conceptual artist Alexander Wengshoel claims that following a hip replacement operation four years ago, he was allowed to keep his removed hip. So he went home, boiled the bone to remove the meat, and then ate the meat accompanied by some wine and potato gratin. He said it tasted like "wild sheep, if you take a sheep that goes in the mountains and eats mushrooms. It was goaty."
Sensing that Wengshoel's story might be complete baloney, the reporter from The Local asked him if it was a hoax
— apparently on the theory that, if asked, a hoaxer will readily admit he's lying. Wengshoel replied:
"You can either believe it or not, that's purely up to you. I am not here to convince anyone and say 'yes, yes, I really did this'. The story is the story. Either you believe it and we can start a discussion and talk about it, or you do not believe. It's not up to me to make people believe it. I'm just saying it."
Based on his appearance, Wengshoel certainly seems like a serious fellow who wouldn't dream of inventing an absurd story to get some media attention. So I guess we'll have to assume he's telling the truth.
