 Many people recognize BBC television's test-car depth. However, when it was broadcast in Scarfoca an old woman would inexplicably appear in place of the young girl, as soon as parents left the room. According to legend, if she turns to look you in the eye, you are fated to die beneath an overloaded lorry which will topple over, crushing you with its consignment of industrial safety equipment, find out if you are cursed here. Children called the woman old chattox and she was believed to be a 17th century witch whose spirit had been unintentionally revived and broadcast by a ill-top TV transmitting station built on the site of her execution. She frequently flouted broadcast guidelines and undermined the BBC's attempts to avoid product placement by advertising the services of a bold castrator who had been dead for nearly 400-100 years. Below, photographs of old chattox taken by viewers between 1970 and 1978. Old chattox wrote out demands on her blackboard, which children felt compelled to obey, top. She also drew occult or satanic symbols designed to mesmerize and indoctrinate young viewers. Some of her messages were seemingly nonsensical, though many people believed they were cryptic descriptions of future events. Bottom. Bubbles, the clown who appeared in the BBC TV test card, was very popular in the 1970s. He even had his own animated public information series and range of merchandising including toys, t-shirts, mugs, greetings cards and surgical instruments. However, in 1978, parents became alarmed when they discovered that many of the products were possessed by the spirit of an embittered XTV presenter, Simon Gamora, who had hosted a daytime programme called Housewife vs Anaconda, before it was suddenly cancelled without warning. It wasn't until several months after Gamora's suicide that Bubbles' merchandising began displaying supernatural activity. For example, the Bubbles' birthday greetings card, as pictured above, appeared to be perfectly normal when it was sold in the shops. But, once it had been given to a child, Bubbles would transform during the night into a demonic vulgar entity that shouted out vulgar profanities and urinated at anyone who came within shot. Gamora's body was eventually exhumed, and his feet were fitted with oversized, concrete-filled clown shoes, so that his spirit could no longer wander the earthly plane.
