Former professional baseball player Torii Hunter might have excelled on the field, but his investment strategy certainly missed the mark. In the early 2000s, Hunter reportedly invested $70,000 – the equivalent of around $113,000 (£83k) in today's money – into a company that supposedly made inflatable rafts designed to sit under items of furniture.
The idea was that if your house started to flood, you could inflate the rafts and your furniture would stay safe and dry. Ironically, however, the money Hunter 'sank' into the project was never seen again.
