One Piece Chapter 24, page 4: Things That You Can't Lie About

After calming down, the boys sit at the table with Nami, Zoro, and Luffy. They explain that Usopp left the shop saying, "It's that time again." They reveal that he went to the mansion where a sick girl lives. Luffy asks why he goes there, and Nami asks if it's to tell lies. The boys happily confirm, saying, "THAT'S NOT BAD! ACTUALLY, IT'S GREAT!" Luffy is confused, asking, "ISN'T THAT A BAD THING TO DO?" but the kids insist it's very good.
