One Piece Chapter 4, page 7: Chapter 4: The Great Captain Morgan

At the Marine base, soldiers are carefully raising a giant statue of Captain Morgan. Helmeppo complains loudly to his father, demanding to know why he isn't hunting down the "brigand" who hit him, boasting that even his father has never laid a hand on his face. Morgan asks if Helmeppo knows why he's never hit him. Before Helmeppo can finish saying "because I'm your beloved son," Morgan brutally punches him, declaring, "It's because you're an idiot son who's not even worth hitting!!"
