Just because you're filthy rich and famous and in the public eye doesn't mean you don't have a mind full of brilliant ideas that could change the world, or at least warrant the issue of a patent.10. Michael Jackson – Anti-Gravity Shoes

When you think Marlon Brando, you don't instantly think conga drums, right? Well, apparently the talented actor was a huge fan of creating a beat and hitting the drums. So much so that he developed a revolutionary tuning system for the drum. Brando was granted a patent for a drummer head tension device that would stretch a drum's skin once it lost tension. According to his patent, a motor is attached to the drum, allowing "an individual to quickly and reliably tune the drum either manually, by operating a motor, or automatically by way of a tuning circuit." Neat, huh?
Marlon Brando not only dreamed up ways to improve the humble conga drum, he also invented a special exercise shoe. According to Kevin Costanza, the late actor's patent attorney, "he [Brando] had these shoes that you can wear in the pool that would increase friction as you walk on the bottom of the pool to give you a better workout." Sadly Brando never lodged this invention with the patent office. However his attorney is pushing forward with Brando idea and hopes to start selling the crazy, friction-loving pool shoes soon.
