As the lists have now closed without any formal entries except those of antianticant, which have been ruled out of order by Judge anticant on grounds of consanguinity, Judge anticant now pronounces his own verdict as to the identity of billstickers. To paraphrase Oscar Wilde, billstickers is:
the inscrutable in pursuit of the ineffable.
If antianticant's entry had not been disqualified, the award would have gone to his surmise that billstickers is the Boojum, from Lewis Carroll's poem "The Hunting of the Snark". The Boojum is thus described by Martin Gardner, annotator of Lewis Carroll's works: "The Boojum is more than death. It is the end of all seaching. It is final, absolute extinction. In a literal sense, Carroll's Boojum means nothing at all. It is the void, the great blank emptiness out of which we miraculously emerged; by which we will ultimately be devoured; through which the absurd galaxies spiral and drift endlessly on their nonsense voyages from nowhere to nowhere."
Recognise yourself, billstickers?
