I don't get. I see the Nichijou and parody tag, but I still don't understand. :/
The parody is that one skit where Yukko was riding the train and a series of unfortunate events leads to her getting publicly embarrassed while a younger girl struggles not to laugh. It ends with Yukko meeting with Mai and both puts on Halloween costumes which is where the younger girl breaks while the gundere girl remarks that Halloween already ended. This specific scene is either when Yukko stood at the side of the train that was facing the opposite side of the exit or when Yukko bumped into a statue and apologized to it thinking it was a human.
