...and I'm really glad we found out a way for Anna and Ryoko to get involved and also to fill in some time based on the fact that there's not enough manga material available but there's also a reference to that classic family anime in this episode that I think a lot of people will get even if I don't explain it but it's been a chance to think about how animators back then had to put so much care into drawing each cel by hand instead of doing it digitally like we do now which is pretty cool and that's the deal with episode 11.
That makes it an obvious prank. 
No need to open it at all.
.هذا يجعلها خدعة واضحة. لا داعي لفتحه مطلقا
Dann brauch ich gar nicht erst aufmachen.
Ist garantiert ein Streich.
Es una broma, no hay por qué abrirlo.
Es una broma, no hay por qué abrirlo.
Même sans l’ouvrir,
je sais que c’est une blague.
È chiaramente uno scherzo.
Non c'è bisogno di aprirlo.
Eu não vou abrir essa porcaria.
Tá na cara que é alguma pegadinha.
То есть очевидный розыгрыш.
Я не хочу открывать.
