Bravest Man Ever Lets Tigers Attack Him for a Living

Randy Miller is one tough dude.

The 45-year-old Miller is not your run-of-the-mill animal trainer. He actually trains tigers to attack him.

Miller is so adept at working with tigers he's made a career training them for some big flicks, including 'Gladiator,' 'Transformers 2' and 'The Last Samurai.'

Check out this video of Miller in action as he deals with the hazards of the job. He's got so many moves we wouldn't be surprised if he helped Justin Bieber fend off teen girls.
