Calling all pirates

Gather 'round, ye swabs. I've got some news for ye. Deep-sea explorers have found a large pile of treasure off the coast of Florida. They think it might be the biggest ever found. They are estimating the treasure will be worth $500 million.

Also, pirates off the coast of Somalia (they call themselves the Pirates of the African East Coast) seized two South Korean fishing boats. Thirty people have been taken hostage.

Here's a question: what are a bunch of South Koreans doing fishing off the coast of Somalia in dinky little boat?
