One day Holmes and Watson are flying a dirigible balloon. It is foggy around, they have lost their way. Suddenly they see - a shepherd is grazing sheep below. The men are very glad and shout:
- The dear, tell us, please, where we are now?
- You are in the dirigible balloon.
- I understand... - Holmes says. - We are flying over Russia.
- But why? - Watson is surprised.
- It’s elementary, Buddy! Only a programmer could give such an exact and useless answer at the same time. And only in Russia programmers can look after sheep.
