You never know when he's 
gonna do something evil.
لا أحد يعلم متى يقوم بفعلٍ شرّير
Wir können nie sicher sein,
wann er die nächste Schandtat verübt.
Quién sabe cuándo hará algo vil.
Quién sabe cuándo hará algo vil.
Qui sait
quand il commettra l’irréparable ?
Non sappiamo quando si voterà al male!
Nunca se sabe quando
ele vai fazer algo maligno.
В любой момент
может нож в спину воткнуть!
