Honestly... When is that monster 
in glasses coming back?
Herrje, wann kommt das Ungetüm
mit der Brille zurück?
¿Cuándo rayos piensa volver 
el monstruo de lentes?
Quand va-t-il donc daigner rentrer,
ce monstre à lunettes ?
Accidenti... 
quando torna quel mostro con gli occhiali?
Puxa... Quando aquele 
monstro de óculos vai voltar?
Ну и ну. Когда вернётся
это очкастое чудище?
