This week we explore narrative causality, which, like the life force and belief & metaphor on the Disc is stronger because of the rather tenuous nature of reality there. We also briefly consider the beliefs of Sir Samuel Vimes, Lord Havelock Vetinari, the Nac Mac Feegle, trolls, and Ponder Stibbons. Now that strains the nature of reality. It helps if you remember that it's probably all down to bloody quantum in the end.

This week's trivia question: Which Discworld novel with a one-word title was published first. Easy peazy, right? Which reminds me, there is one character in all the Discworld novels, as far as I can remember, who ever utterz the phraze easy peazy. And who has that strong Uberwaldian accent, I hear you ask. Think the Ankh-Morpork Times and you'll probably guess that it's Otto Chriek. Ooops gave that one away didn't I. Incidentally if you pronounce Otto's full name a few times you'll hear the pun there. What should you do when you meet a vampire. Well, you Otto Chriek. Ba dump bump. Please send correspondence, including complaints about this bout of egregious pun-referencing, to [email protected]. That's where you can send your answer to this week's trivia question as well. Just be aware that all complaints are referred to the Ankh-Morpork Times' complaint department, Rocky the troll.
