To the man's credit, he holds his position for 10 seconds before the crocodile obviously gets sick of his crap, snapping down on the man's head and violently thrashing him around.
The zookeeper can be heard letting out a terrifying scream as the crocodile slides its way back into the water.
What makes this story even crazier is that before the show began, the man boasted and showed the crowd previous wounds previously sustained by the crocodile, including a missing finger.
That, my friends, is why you never talk sh*t in front of a crocodile. (And why you should never stick your head their mouths.)
