Beria, the chief of Stalin’s secret police, is waiting in front of Stalin’s office for an audience. Suddenly, the doors slams open and a general comes out, visibly upset. Not noticing Beria, he utters to himself while walking out of the room: “That turd with mustache!”. 

Beria calmly enters Stalin’s office and after greeting him, he informs Stalin with a grave face about the general’s utterance. After hearing this, Stalin picks up the phone and asks to speak to the general. 
- I heard you said the words “turd with mustache” as you left my office. Who did you mean by that?
- Hitler, of course, answers the general.
- Hitler, you say… Thank you.
Stalin then puts the phone down and turns towards Beria:
- And who did YOU mean, comrade Beria?
