13 July. In 1984, a street in Fort Worth, Texas, developed a 20ft long, two-foot-wide bulge. It moved from side to side like a giant worm before disappearing after about an hour. 'It seemed almost alive,' said a fireman. 'What spooked me was that there wasn't even a crack in the road.' Street crews used jackhammers to break through two inches of asphalt and four inches of concrete, but found no evidence of a gas build-up that might have caused the bulge. Six months later the story emerged in an American tabloid under the headline: 20 Foot Earthworm Terrorizes City ... Swallows Dogs.
