Goku Sayonara Zetsubou Sensei Season 3 Episode 4

How I Became a Real Human / Celebrated Pedigree / Doctor Kahogo Part 2

Chiri notices Nami wearing brand new trainers in the rain and gets annoyed when people don't consider TPO (a wasei-eigo term meaning Time, Place, Occassion). Nozomu laments that some people do an incorrect TPO when compensating for another TPO. When ume no hi comes, Nozomu ponders that its not a convenient holiday for prefectures of Japan that aren't next to the sea. The discussion moves onto the morals of celebrating things others can't cheer about. The gang decide to have a 'chimerical holiday', involving as little fun as possible. After escaping from the Excessive Care Guardian's Club, Nozomu finds all his leisure options restricted due to excessive care. He then notices that his body double has been benefitting everyone in his place.
