Most pirates spend their downtime at their favorite watering-hole, dockside brothel, or the local jail awaiting trial.
On the other hand (assuming you have another hand, and not a hook), Walter the Pirate had always dreamed of winning an Olympic gold medal.
He was a pretty good windsurfer, and none of his shipmates could beat him at Ping Pong, but he was best at freestyle swimming.
But what national team would sponsor him?
France?
England?
They had bounties on his head.
Eventually, Somalia sponsored him. (Somalia loves pirates), but he was disqualified for having a dagger clenched between his teeth.
