Nishikata receives his first cell phone and can't wait to play tricks on Takagi-san.
He sends her a scary video to frighten her, but it doesn稚 quite work. 
As usual, Takagi-san has the upper hand when it comes to teasing...
I know! Your dad?
عرفت! أبوك؟
Ich weiß! Mit deinem Vater?
¡Ya sé! ¿Con tu papá?
¡Ya sé! ¿Con tu padre?
Je sais ! C’était avec ton père.
Ah, ma certo! Era tuo padre?
Ah, já sei! Foi com o seu pai?
А, знаю, с отцом?
