One Piece Chapter 8, page 17: Nami

The three pirates surround Luffy, brandishing their swords. One of them sneers, "ISN'T THAT RIGHT... BOSS!? THAT MAP BELONGS TO THE FEARSOME PIRATE, BUGGY THE CLOWN!!!" Luffy tries to speak, saying, "HEY..." but one of the pirates suddenly slashes at Luffy's head with his sword. The blade strikes Luffy's straw hat with a sharp "CHWNK!!!" sound. Luffy's expression instantly turns dark and serious. He catches the sword and says in a low, threatening voice, "DON'T TOUCH... THE HAT!"
