One Piece Chapter 22, page 26: YOU ARE A RARE AND PRECIOUS ANIMAL TOO

Nami is devastated for Gaimon, pointing out the tragedy of him guarding empty chests for twenty years. Suddenly, Luffy bursts into loud, cheerful laughter. He tells Gaimon not to be disappointed, pointing out that meeting them after twenty years is a great thing, and jokes that if it had been thirty years, Gaimon might already be dead. Luffy then invites Gaimon to join his crew and search for the One Piece together.
