Again, I’ll give a literal version: But if you have to do with them, they’ll hook you name and surname, and the person who made you, with the nib of that pen, and you’ll never extricate yourself from their horrible books, nailed in debt.
Ma se avete a far con essi, vi uncinano nome e cognome, e chi vi ha fatto, col beccuccio di quella penna, e non ve ne districate più dai loro libracci, inchiodati nel debito.
