puerile humor, all caps Melville quote
so this ship captain walks into a bar and his fly's open
so the barkeeper says sir everyone can see your dick so he says
AYE AYE TWAS MOBY DICK THAT DISMASTED ME MOBY DICK THAT MADE A POOR PEGGIN' LUBBER OF ME FOREVER AND A DAY! AYE AND I'LL CHASE HIM AROUND GOOD HOPE AND ROUND THE HORN AND ROUND THE NORWAY MAELSTROM AND ROUND PERDITION'S FLAMES BEFORE I GIVE HIM UP AND THIS IS WHAT YE HAVE SIGNED FOR MEN TO HUNT THE WHIT....
oh wait, the joke's supposed to be "he has a ship's wheel on his penis"
