Our lecturer in philosophy told about his professor (also, respectively, in philosophy) such a story.
They buried this professor in the harsh years of personality cult (a year somewhere in 38). Among other things, they were forced to fill out some lengthy questionnaire, where among the other FIO and fifth points (by the way, on the fifth item was "So yes!") there was a question: "What foreign languages do you know?".
What language should a philosopher speak? Latin is well! So he wrote: "Latin". I don't know how terribly he was treated there and how long it lasted, only gave him 10 years in the end.
And he sent them from call to call, like a true Latin spy!
