A postmodern prank
Live rattlesnakes released in theater during screening of Snakes on a Plane.
"That to me is very scary," herpetological association representative Tom Whiting said. "I would hate to be watching a movie about snakes and have a rattlesnake bite me."
I'll go out on a limb here and say that the reporter didn't need to call a herpetologist (zoologist specializing in reptiles) to invest that quote with credibility.
