The CIA spy was fluent in Russian, had perfect Cyrillic handwriting and could drink buckets of vodka. He was dropped on the outskirts of Moscow and spoke to a man in the street, “Hello comrade, can you direct me to the centre of town?”
The man looked at him, and walked away. Within minutes, the KGB came and arrested him.
While being interrogated, the KGB interrogators said, “Quit the act, we know you’re a spy.” He couldn’t believe they’d penetrated his disguise and kept up the act.
He finally cracked, “Alright, alright, I’m a spy. I’ll tell you whatever you want, but please just tell me how you knew I was a spy so quickly.”
