Don't go teaching weird stuff 
to someone else's kid!
Setzt fremden Kindern doch
keine Flausen in den Kopf!
¡No le enseñen cosas raras
a niños ajenos!
Dejad de enseñarle cosas raras
a los hijos de otras personas.
N’apprenez pas des trucs pareils
au fils du voisin !
Non insegnate stramberie ai figli degli altri!
Não ensine coisas estranhas
aos filhos dos outros!
Чему вы учите чужого ребёнка?
