Here were my instructions: I was to write a column on nudity, Halloween, or better yet, a combination of both. Simple enough. Same for every major religious and federal holiday that I can think of. And that includes bank holidays.
With Halloween fast approaching, parents of the Western world are once again preparing to send their children out into the night, armed with nothing more than a supermarket-bought costume and a plastic bag, to beg strangers for confectionery. Costumed children generally expect a free treat from the neighbourhood's houses, under the caveat that unobliging houses may be subject to a 'trick', which can range from toilet paper being strewn over the garden to eggs being thrown at the front door. While this may baffle the rest of the more responsible world, trick-or-treating is one of the few remaining celebrated Halloween traditions. This suggests that children must stand something to benefit from disguising themselves as vampires, ghosts, Piers Morgan, and the other general evils of the world. The appeal of free treats may sound like enough, while the use of costumes provides a useful alibi in the event of any inflicted property damage. However, humans are not the only animals to don disguises and mimic others; the natural world has imposters of its very own. By evolving a common warning colouring, other animals learn that the creatures displaying this pattern are unpleasant or toxic. This process happens a lot quicker when dangerous animals have a shared warning pattern, as the strength of the signal is stronger due to the signal being encountered in the wild more frequently. This is an example of Positive Frequency Dependence, whereby a common trait is selected for because the trait becomes more advantageous the more common it is. Because there are so many species involved, the likelihood of a predator eating one of the butterflies increases, and so the predator will quickly learn to avoid all the species that share that appearance.
