One Piece Chapter 2.3, page 8: That Boy "The Straw Hat Wearing Luffy"

Just as the pirates are standing around the barrel, it suddenly explodes outward. Monkey D. Luffy bursts out of the barrel, stretching his arms wide and shouting at the top of his lungs, "WHAT A NICE NAP THAT WAS!!!" The pirates and Coby scream in absolute terror and shock, "WHAT THE HELL?!! AHHHHHH!!!!" Luffy laughs happily amidst the flying wooden shards, saying, "I THOUGHT I WAS GONNA DIE TOO!! HAHAHAHAHA!! LOOKS LIKE I'M SAVED."
