All That Is Fantastic

I've noticed a bit of an odd phenomenon. Every time that I mention some kind of bizarre conspiracy theory someone comes along and makes a comment that it's absolutely true. So the only thing I can see to test this unproven hypothesis is to make up stuff and see if anyone makes the necessary comment to prove the hypothesis.
Now the trouble here is that I've got to find something to use that hasn't been invented before - so this rules out things like the Henham Dragon ( a hoax, but I believe once attributed to a crocodile that had escaped from a menagerie and was making merry with the folk of the area), or rescue missions sent by the US President to save the crew of a WWII bomber stranded on the moon. Then there is the vast and oddly attractive area of strange deaths - people electrocuted whilst fishing with the aid of the Polish national grid and falling into the water with the current still on or someone being squashed by an aircraft drop tank whilst sunbathing. However none of this has the necessary gravitas.
Therefore if in doubt the only safe option is to open the files of cryptozoology and celebrity gossip and announce that Colchester Zoo has a covert breeding programme for Chupacabra and that the surprise in Harry Potter and the Vast Advance Author's Fee is that Harry's mother was none other than Linda Lee Potter (the late Daily Mail columnist)
