Interview with the Somali pirates. They didn't say "Yarrgghh, matey" and they like spaghetti.

“We just saw a big ship,” the pirates’ spokesman, Sugule Ali, told The New York Times. “So we stopped it.”

...In a 45-minute-long interview, Mr. Sugule expounded on everything from what the pirates want — “just money” — to why they were doing this — “to stop illegal fishing and dumping in our waters” — to what they eat — rice, meat, bread, spaghetti, “you know, normal human-being food.”
He said that so far, in the eyes of the world, the pirates had been misunderstood. “We don’t consider ourselves sea bandits,” he said. “We consider sea bandits those who illegally fish in our seas and dump waste in our seas and carry weapons in our seas. We are simply patrolling our seas. Think of us like a coast guard.” LINK

Well, then. That certainly clears it up.
