A slow-motion video going viral shows a man touching an alligator's tongue with his hand in a terrifying daredevil stunt.

Jason McDonald , 34, thrusts his palm into the jaws of "Elvis" at the Colorado Gator Farm in Mosca, Colorado. He then quickly strokes the reptile's tongue, and removes his outstretched fingers just before the creature snaps its mouth firmly shut.

McDonald, a gator wrestler who runs his own video company, told The Huffington Post that he has worked with Elvis on several stunts over the years and almost been caught twice -- but not on this particular occasion.
