In my research during a (somewhat fruitless) comment transaction here on HN about pirates (actual salt sea-dog type pirates) I came across the following story which I think some of the people commenting here might find interesting... I'm in the process of writing this up as a sea shantie:

A pirate captain by the name of Bartholemew Roberts captured a British official by the name of Plunkett who had double crossed a company of pirates and shot them down under a banner of truce - few things could enrage a pirate more! Old Roberts was incensed and, upon finally capturing Plunkett, took to cursing him in the most foul and heinous of language - of which a pirate dialect was primarily composed. Seeing himself a dead man and with no other hope left to him, Plunkett stuck out his chest and being a proud and experienced Irishman, gave back a measure and then some more in such illbegotten slights of character on Old Roberts name that the crew hung limp and incapacitated with laughter. The whole exchange inspired such a regard for Plunkett's tongue that dispite his crimes against pirates, the whole company agreed to send him on his way no harm done.
