A 27-year-old animal handler in Thailand is lucky to be alive after a dangerous stunt went TERRIBLY wrong on Sunday.



In the middle of a show for a bunch of tourists, he stuck his head in a huge crocodile's MOUTH . . . which he's apparently done many times before.



But this time, the crocodile immediately clamped down on his FACE and started shaking him around.  Luckily, it was only for a second, and the handler survived without any serious injuries . . . other than some major scars I assume.
