When the devil hears a shaker of flavour enhancement flakes or crystals fall upon your table and spill, he finds him self compelled to sneak up behind you and whisper magical profanities into your ear. It is for this reason that you throw a pinch of salt over our shoulder and into his evil eyes so that he walks, cursing to him self, out the door. If it is pepper that you spill, a pinch of it must be sprinkled upon your shoulder so that as the devil prepares to utter his hideous, magical swear-words, he begins to sneeze uncontrollably. Neglecting to prevent this malicious whispering will make you an agent of his apocalyptic plans.
Home is where the fart is.
