I... I don't think there should be any politicking at all, honestly.
Anyway: The Old Man and The Mayor
The Mayor is called to sea by whatever booty he is tasked to obtain. Unfortunately, The Mayor lost his personal Cruise Liner in a wild and hilarious bet, thus forcing him to acquire a new vehicle for nautical adventuring.
Enter The Captain. Or rather, enter the run-down bar The Captain is telling long-winded stories in. The Mayor demands of The Captain his ship, the Whistling Whore; The Captain demands a great and terrible price of The Mayor for his services: money. The Mayor and The Captain haggle... with piledrivers. Mayor wins, Captain agrees to take him wherever he wants.
And so into The God Damn Ocean they go. Unfortunately, it's Giant Crab season in the Gulf of Mayor-O. Fortunately, it's only one crab. Unfortunately, it's still a pretty big damn crab. Boss Fight ensues.
Later that night, The Mayor takes a mighty piss. This offends Triton, God of the Sea. And so, a contest is put forth: a pissing contest, between Man and God. But The Mayor is no great fool, and he understands that he as a mere mortal cannot possibly out-piss a God. He speaks with The Captain, and is recounted an old sailor's tale of a seaman that drank from a strange Golden Goblet he found in a lagoon, and when that sailor went to relieve himself his urine became as a missile.
The Mayor, using his keen decision making skills, deduces the location of the Golden Goblet, and to there quickly aboard the Whistling Whore they sail.
This is where the scenario's dungeon is. Anyway, run around, kill things, find your way to the Golden Goblet and battle with the Boss monster protecting it.
Fast forward to the eve of the contest. Triton goes first, points his massive member skyward, and pisses so hard that he creates a massive storm. The Mayor, having had drank several gallons of whiskey prior straight from the Golden Goblet, releases a golden stream so powerful that he cuts the sky itself in twain.
Triton is furious, and demands of The Mayor the secret to his whizz. The Mayor indignantly tosses the Golden Goblet to his feet. Triton examines the mysterious artifact, and then proceeds to fall to his knees and weep. The Golden Goblet, you see, though once a powerful and magical item, had long ago lost its great power. The Mayor had the power all along. Defeated, Triton bestows upon The Mayor the treasure he sought.
