A prankster in Arizona released two live Diamondback Rattlesnakes in a theater full of people watching Snakes on a Plane. The following link has a video of the news coverage of this incident: CollegeHumor Movie: It's irresponsible and dangerous, but releasing poisonous snakes in a theater showing Snakes on a Plane is undeniably funny.
After reading some comments on this article being bogus, I did a search on Google and came up with this link: 'Snakes in a theater' turns out to be hoax. From the article, Quote:
"There is some shred of truth to the story, Phoenix police Sgt. Joel Tranter said. A 10-inch-long rattlesnake was found Friday in a hallway at AMC Desert Ridge 18, near Tatum Boulevard and Loop 101. But it likely slithered inside on its own, Tranter said."
"An AMC spokeswoman told the news organization Reuters that the rumors were true, but Tranter has been refuting the story to news outlets from across the U.S."
So, there you have it. To quote a saying from Paul Harvey "... and now you know [pause] the Rest of the Story."
