The Ass and the Crab

An ass keeps crabbing against a crab that has just dug a manhole nearby, concerned about rumors that might fly, tarnishing his reputation thereby, for when folks ponder, ask in wonder about that dark hollow in the ground and see in the vicinity only him and no one else around, they'll surely wink and snicker, and rib each other with a question so crass: Prithee, what do you call that hole obviously belonging to that ass? Indeed, when folks have finally made up their minds and mouths about you, no finger-pointing will ever do, the damage done you can't undo !
