On avoiding the End of the World
My advice to you - should you stumble across signage such as this, and you don't want to accidentally trigger a global apocalypse in which all mankind in consumed in an inferno of death, destruction and sarcasm - is not to turn right.
Sadly, I turned right the other week, and it took them days to get all the wing-ed and hideously tentacled creatures back through the dimension rift. Let that be a warning to you all.
Actually, The Worlds End - despite the dreadful apostrophe abuse - is a rather nice pub in Almer in Dorset. Just don't ask for the Shoggoth's Old Peculiar. It's off.
