One Piece Chapter 1.1, page 13: Romance Dawn (Version 1)

In the flashback, Shanks looks at young Luffy and says, "LISTEN, LUFFY. YOU SAY YOU LOVE THE SEA AND ADVENTURE, AND I VALUE THAT SPIRIT. BUT IN EXCHANGE FOR THAT FREEDOM YOU RISK YOUR LIFE!!". His crewmates agree, "CAPTAIN SHANKS, WITHOUT THAT WE WOULDN'T HAVE DREAMS, RIGHT?" and "YOU HAVE A STRONG WILL TO GO OUT TO SEA IN A SHIP EVERY DAY DESPITE BEING A HAMMER." Meanwhile, young Luffy is sitting by a treasure chest, eating a strange, swirly fruit. He makes a disgusted face, saying, "HORRIBLE." and "WHAT IS THIS?". Shanks and his crew suddenly notice and freak out. Shanks screams, "OI!!! YOU! ISN'T THAT THE 'GOMU GOMU' FRUIT!! HE ONE WE STOLE FROM AN ENEMY SHIP! THE FRUIT FROM THE ILLUSION TREE THAT BEARS FRUIT AT MOST EVERY 50 YEARS!!". Shanks grabs Luffy and shakes him violently, yelling, "EATING THAT MAKES YOU UNABLE TO SWIM!! FOR-EVER!!! ENTERING THE WATER MAKES YOU LOSE YOUR ENERGY!!". Luffy, completely unfazed, smiles and says, "GOMU GOMU FRUIT?...WEIRD!! TOO BAD, I GUESS I ATE THE FRUIT FROM THE ILLUSION TREE." Shanks and his crew scream in horror, "NO WAY!!!" and "YOU IDIOT!!!".
