One Hairy Day (みんな危機一髪 Minna kiki ippatsu?) is the 117th chapter of the manga and the fourth chapter of the Principal Kuno Intro Arc. All the students chase after Kuno trying to shave his head so they can find the coconut, but Akane feels bad about they way they are treating him. Ranma decides to change into the Pigtailed Girl and asks Kuno to shave his head on his own, but that does not work either.
