One Piece Chapter 9, page 25-26: Chapter 9: Femme Fatale

Nami enters the tavern, dragging the tightly bound Luffy behind her and tossing him onto the floor with a heavy thud ("SP", "UMP", "OOF!"). Nami stands confidently before Buggy and announces, "Captain Buggy! I've captured the thief! And here's your map!" Buggy, sitting on his throne, looks at her with suspicion, "Hmm... You're returning the map? What's all this about?" Luffy, lying bound on the floor, realizes what has happened and yells angrily, "HEY! YOU TRICKED ME!" Nami simply looks back at him and playfully sticks her tongue out.

Nami explains her actions to Buggy, putting on a show: "I had a dispute with my employer! He's an idiot, so I thought I'd join up with you!" Buggy stares at her in silence for a moment ("Huh?...") before bursting into a loud, booming laugh: "HAHAHAHAHAHAHAHA!!! HA HA HA HA HA HA HA!! Buggy, thoroughly amused, says, "Idiot, eh? You've got spunk! I think I will let you join my crew!" Meanwhile, Luffy is thrown into a wooden cage, which shuts with a loud "KLANG!!". He grumbles to Nami, "Just forget about joining my crew, now!" Nami turns away with a satisfied smile, thinking to herself, "Infiltration accomplished! Now to grab Buggy's treasure and the map of the Grand Line......and make a quick getaway!!"
