Hilarious.
I always wonder what happens when someone has a heart attack in something like this.
I remember the sci-fi channel here used to have a prank show that was fairly elaborate. One prank in particular always jumps to mind where they faked an alien abduction. Four or five people where in a car and only two of them were in on it. I couldn't help but think, "If someone did this to my dad, he'd pull a .45 out of the glove box and some poor stage tech would have a new hole in him or her".
