This almost looks like one of those clickbait articles you see around the internet that tries to suck you in with a false story, but this one is as real as could be. This guy actually decided to build a fully functional electric guitar out of his uncle's skeleton. Apparently, the uncle was the one who got this guy into heavy metal music, and as a way to repay him, the nephew decided to let his uncle keep shredding.
You can read more about this ridiculous project online, but we wouldn't suggest trying it yourself. The quality of a skeleton-based guitar doesn't compare to the hassle it takes to build one.
