One Piece Chapter 2.3, page 13-14: That Boy "The Straw Hat Wearing Luffy"

Coby sadly explains, "YEA... I DON'T WANT IT ANYMORE. I WAS GONNA RUN AWAY IN THIS, BUT I DON'T HAVE THE GUTS TO DO IT... LOOKS LIKE I'M GONNA BE A CARETAKER MY WHOLE LIFE. ALTHOUGH... I DO HAVE SOMETHING ELSE I WANNA DO." Luffy bluntly says, "THEN YOU SHOULD LEAVE." Coby panics, "NO... NO I CAN'T IT'LL NEVER WORK! WHENEVER I THINK OF ALVIDA-SAMA FINDING OUT, MY LEGS TURN ALL MUSHY...!! I GET SO SCARED...!!!" He explains that he accidentally boarded her ship two years ago while out fishing and had to work to survive. Luffy smiles and says, "YOU'RE PRETTY STUPID AND USELESS. AND YOU SEEM KINDA WIMPY TOO. I DON'T LIKE YOU." Coby sweatdrops, laughing nervously, "EH... EH HEH EH HEHEHEH EH HEHEHE HEHE...!! HOW BLUNT. BUT... YOU'RE RIGHT... IF ONLY I'M BRAVE ENOUGH.........HEY... LUFFY-SAN, WHY ARE YOU SAILING?

With a massive, confident grin, Luffy declares, "I WANT TO BECOME THE PIRATE KING!!!" Coby's eyes widen in absolute shock, and he screams, "EH......! WHA?!! WHAT?!! 'PIRATE KING' WAS THE TITLE OF SOMEONE WHO HAS HAD EVERYTHING IN THIS WORLD!! ARE YOU TELLING ME THAT YOU'RE LOOKING FOR THE 'WORLD'S GREATEST TREASURE'...UHM THE 'ONE PIECE'!?
