"The Crabfish", (known also as "The Sea Crabb") an English folk song dating back to the mid-1800s about a man who places a crab into a chamber pot, unbeknownst to his wife, who later uses the pot without looking, and is attacked by the crab. Over the years, sanitized versions of the song were released in which a lobster or cray grabs the wife by the nose instead of by the genitals or that imply the location of the wounds by censoring the rhyming word in the second couplet. For instance, "Children, children, bring the looking glass / Come and see the crayfish that bit your mother's a-face" (arse).
