Meet Jerry Jalava. Jerry is a Ducati-riding computer engineer from Helsinki. In 2009, after an accident on his bike left him with part of his finger missing, Jerry decided to do something useful with his prosthetic fingertip.
He turned it into a USB drive.

I gotta say… this really puts to shame my desire to have a Luke Skywalker arm compartment that I then fill with fruit snacks.
According to BuzzFeed, it’s a two-gig drive. The missing finger is his ring finger, by the way, which just barely misses the real joke … thumb drive.
