One Piece Chapter 1, page 43: Romance Dawn

Luffy thrashes in the water, unable to swim: "Jerk!! Brat... That guy is scum! And I didn't even get one punch in! Darn it!" Higuma watches him drown from the boat, laughing: "Ha ha ha ha ha!! Did you see the look on those pirates' faces? I broke a bottle over his head, and not one word of protest!! How pathetic!! Ha ha ha ha ha!! Cowards like that make me sick! I wanted to kill him!" Luffy screams back through the water: "Take that back! Take back what you said about Shanks!! He's not a coward!! Stop talking bad about Shanks!!!!"
