One Piece Chapter 27, page 14: The Plot

The guard with glasses draws a gun, shouting, "Die!" as he aims at Usopp. Usopp quickly ducks and pulls out his slingshot, stretching the band back as he mutters, "Pull out... stretch..." He fires a shot directly into the face of the guard with glasses, who screams, "Argh!!" as he is knocked backward. The slick-haired guard curses, "Damn it!" but Usopp quickly turns his slingshot toward him, stretching the band again.
