One Piece Chapter 23, page 7: Captain Usopp Enters

Hanging upside down from a tree branch, Usopp congratulates himself on his morning antics. "I AM VERY HAPPY... I'VE DONE ANOTHER GOOD DEED TODAY! I'VE HELPED ADD SOME EXCITEMENT TO THIS BORING VILLAGE!" Suddenly, a rustling sound ("SFX: GASA...") alerts him. Two young boys appear below the tree, shouting, "AH! THERE HE IS!" Usopp drops down, saying, "HUH? OH OH! IT'S YOU GUYS!" The two boys strike a dramatic pose, holding wooden swords. One is introduced as "VILAGE BOY NINJIN" and the other as "VILAGE BOY PIIMAN". They salute and declare, "USOPP'S PIRATE CREW READY FOR ACTION! CAPTAIN USOPP! GOOD MORNING!"
