There is this new show on Comedy Central called "Strangers With Candy". It's
pretty hilarious. Anyway, on the one episode, there is a police officer
giving an oration to a group of high school students about drug abuse. He
dims the lights to show an old scratchy black and white film. The title comes
on, "DRUG RELATED DEATHS", and then there is a peaceful looking loaf sitting
in the desert, which without warning blows  up into a bazillion pieces!
