Forget about "War of the Worlds"! Read this incredible story in "Manitoba History", Number 13 "The idea was to stage a fake Nazi invasion of Manitoba. The “Nazis” were to occupy and administer the province for the rest of the day. The key was realism. One couldn’t ignore these Nazis any more than real ones. (...) It was an incredibly realistic invasion, yet, aside from a soldier who sprained his ankle and a Miss Gorin who cut her thumb in her blacked-out apartment, there were no casualties. (...) Official 'laughing classes' were to be set up as soon as possible to better instruct the population in German humour. "
