On lying doctors
The Haruspex has a little joke voice line in Pathologic that is based on a wordplay in Russian, so the English translation omits it entirely: "Ты врач, а я знахарь. Ты врёшь, а я знаю".
Its literal translation would be "You're a doctor, and I'm a medicine man; you lie and I know". Of course, it doesn't make any sense without the Russian context.
First, the Russian noun врач (doctor, medic) can be seen as being formed from the verb врать (to lie) with a suffix -ч (someone who does something professionally) - apparently, the verb used to have a wider meaning, one that included speaking in general, as well as spoken spells (called "zagovor"). Another example of the suffix used that way would be the word ткач (weaver) formed from the verb ткать (to weave).
Thus the word врач, which means "doctor", can be etymologically taken to mean "professional liar" (of course, no native speaker thinks of this when using the word for its intended meaning).
Second and similarly, the noun знахарь (medicine man) is formed from the verb знать (to know). So in Russian it's not's a "medicine man" but a "knowing man".
And this is how the original joke works - the doctor lies, but the medicine man knows.
PS: another profession name that's funny that way in Russian is жрец - a [pagan] priest. It's pretty obviously formed from the verb жрать (to eat greedily and/or messily).
