We all know Jay Leno is a comedian and a car enthusiast, but probably didn't realize he's also a crazy thrill-seeking stuntman. The former Tonight Show host was a guest on comedian Spike Feresten's podcast, Spike's Car Radio, and shared an unbelievable video of him hanging onto the nose of a plane while it was flying. His friends were piloting the small plane and he thought it would be funny -- and it was. It was also really insane.
