If you can't be arsed clicking the link, it goes a little something like this:
Police and teachers who told a group of Californian high school students that two dozen of their classmates had been killed in road smashes had to admit it was just a hoax when the teenagers became hysterical with grief.
Hahaha, good one teachers and kudos to the police for jumping on board. It's like an awesome April Fools' Day prank, except not awesome, and not in April.
It's also like that time I decided to teach my little sister about fire safety. Our house burnt down and my sister is dead, but if she wasn't, she sure wouldn't play with matches in a hurry.
