Further thoughts on the odd humor of Flann O'Brien

There are at least 2 aspects to the strange humor of Flann O'Brien's The Third Policeman - a work that, btw, must have been a huge influence on Monte Python, not only w/ its hilarious patches of dialog and focus on bewildering eccentrics but right down to the title. First, the many references to the philosopher de Salby, about whom the (unnamed) narrator is writing treatise that he hopes to self-publish (and participates in a murder and botched robbery to get the funds to do so): as one "commentator" on de Selby notes, his work brings great joy and solace to all readers because in reading de Selby you realize that of all the "nincompoops" in the world you are not the biggest. Among Selby's theories are that the earth is not spheroid but is shaped like a sausage and that it is impossible to travel from one place to another as any movement is made up of a sequences of still moments placed almost infinitely close together (he arrives at this insight from studying cinematic film, and he tests it by locking himself in a room while he intends to travel to a nearby city, expecting to find himself there when he steps out of the door). The other weird humor comes from the plot itself: The narrator after killing his neighbor is unable to find the box where the neighbor supposedly held his valuables (pretty obvious to us that the co-conspirator ran off w/ the loot) so he goes to the police whom he thinks can help him locate the lost treasure; the police department, however, has only one interest - bicycles (and bicycle theft) - and the officer on duty has the odd idea that, as we are composed of atoms that consist of circulating particles and so are bicycles those who ride bicycles for a long time become "part bicycle" as our atoms intermix (and the bikes gradually become part human as well). This theory is much discussed. Is there any book w/ humor more odd?
