On November 22nd, 1987, two Chicago television stations were hijacked by this strange man in his garage, wearing a Max Headroom max and slapping his own ass with a fly swatter. An accomplice in the background waves around a piece of corrugated tin to simulate background static. It's still pretty nightmarish. The culprit was never caught, making him a hero of American pirate television.
If you want to be spared a glimpse of Max Headroom's bare ass, turn it off at the 90 second mark. Anyone want to guess what Max is saying?
