The principal has found an interesting video on NewTube. She has Rika and Haruo listen to it. Haruo decides that since the singers are more "yes" than "no," he needs to find them and add them to the choir. But the choir will have to catch them first!
You're not a little kid, Sensei.
لست صبيّاً يا سينسي
Ich muss euch bitten,
erst zum Tresen zu kommen.
Vous devez d’abord
vous enregistrer à l’accueil.
Ora non fare il bambino, professore!
Eu preciso que vocês se
registrem na recepção...
Вы же уже не ребёнок!
