Works of Soviet Literature summarized for those unable or too lazy to read them in the original.
Also Stirlitz Jokes and famous quotations:

"People always remember only the end of the conversation".

Stirlitz Joke #2:

Stirlitz went into Müller's office and said, "Herr Müller, how would you like to work as an agent for Soviet Intelligence? The pay is good." Müller, shocked, gives an angry rebuff, then eyes Stirlitz suspiciously. Stirlitz starts to leave, but then stops and asks, "Gruppenfuhrer, do you have any aspirin?" Stirlitz knew that people always remember only the end of a conversation.

I have noticed one inaccuracy:
"Stirlitz likes Marika Rokk"

"Порой с бодуна я ненавидел работу сильнее, чем Штирлиц - фильм «Девушка моей мечты» с Марикой Рокк в главной роли (этот фильм Штирлиц смотрел много раз, ожидая в кинотеатре связного)".

P.S.
"Гестаповцы заблокировали все выходы из кинотеатра. Однако Штирлиц перехитрил их: он вышел через вход…"
