Fan Chucks Helmet at Jerry Jones for Autograph, Hits Him in Head

Autographs are a very important part of the sports world, and some people go to extreme lengths to get them.

A fan at Sunday's Dallas Cowboys-San Francisco 49ers game really wanted Jerry Jones' John Hancock, so the fan launched a helmet from deep and accidentally hit the Cowboys owner right in the head.

You probably shouldn't take a trip to a game the next time this fan is around.
