"Zoomy's thing" has in fact been ghost-written for the past two and a half years by a team of ghost-writers employed by the government, under the supervision of editor-in-chief Emma Bunton Out Of The Spice Girls, who's actually quite a lot cleverer than most people think. It has been important for reasons involving national security to keep up the illusion that Zoomy himself still maintains a daily blog, hence the deception. In fact, it still is vitally important to the security of the nation and the existence of Zoomy himself that this deception not be revealed, but unfortunately there was a typographical error in the latest edition of the ghost-writers' secret instructions, issued today, and now they start with "Do under any circumstances reveal in the blog that Zoomy is in outer space and not at home writing his inane nightly drivel..." so the writers have had no choice in the matter.
Zoomy's occasional appearances on television were all pre-recorded in early 2007, and the results of all memory competitions to which they refer were decided in advance by a committee of government and WMSC officials - Zoomy has been represented by actors (the identical triplets Steve, Dean and Other Steve Bradshaw) at all competitions and the results manipulated by arbiters to conceal the fact that "Zoomy" can't actually memorise anything. At othello competitions he is played by Joel Blackmur in an ingenious disguise made from coat-hangers and gravy. At parties and social occasions, a crude robot is used.
Zoomy's space mission is top-secret and highly classified, but it involves a giant magnet in Bridlington which was built by accident and can't be got rid of due to a refuse collectors' strike, which attacts alien spacecraft from the farthest reaches of the galaxy and have to be continually repelled by Britain's own space program. Since this space fleet consists of one spaceship, and since this was built in the nineteen-fifties and requires course calculations to be done with pencil, paper and a book of log tables, and since all log tables were thrown on a big fire when scientific calculators were invented in 1983, the only person who can fly the ship is someone with a really good memory for numbers.
If any aliens read this blog entry and its revelation that Zoomy is currently taking a week off on one of the least pleasant moons of Jupiter, they'll immediately send their most magnetic spacecraft out on a beeline to Bridlington, take over the country and eat all the ice cream. So now we're for it.
