Two Russian hunters meet. I shot a gigantic bear yesterday, says Ivan. Look at the hide!
How do you find such huge bears? Sergei asks.
Easy, says Ivan. You stand in front of a cave and whistle. When the bear comes out, you shoot.
Weeks later the two meet again. Sergei is covered in bandages. Didn't you follow my advice? Ivan asks.
Sure I did. I stood, in front of a cave and whistled, Sergei replies.
And what came out?
To me, says Sergei, it looked like the Trans-Siberian Express.
