Kisame: "That thing is still bugging you?"
Itachi: "Yeah... it's been here since yesterday." Apparently Sasuke, Itachi's younger brother, is mauling his head.
Kisame: "Then try... THIS!" Kisame reveals Nin-off then sprays it on Sasuke.
Sasuke: "..." Gags then falls off Itachi
Itachi: "Thanks!"
Kisame: "No prob!"
