I direct your attention to the Samuel Beckett novel, Murphy. The hero winds up cremated and his ashes are mixed in the contents of an Irish bar fight. The bag of ashes was used to hit someone in the fight and eventually swept out in the street with the pee and vomit. The instructions from Murphy was to take he ashes to the theater and have them flushed whatever stall (been awhile since I read the novel) for his eternal rest.
