Pranks (Netherlands)

In 1969, the public broadcaster NTS in the Netherlands announced that inspectors with remote scanners would drive the streets to detect people who had not paid their radio/TV tax ("kijk en luistergeld" or "omroepbijdrage"). The only way to prevent detection was to wrap the TV/radio in aluminium foil. The next day all supermarkets were sold out of their aluminium foil, and a surge of TV/radio taxes were being paid.
