Today I saw a truly instructive example of ingenuity.

A boy and a girl in the car. The girl has a nickname "Radio Lighthouse". It doesn’t get stuck for a minute. Wrecked all the way. Tired of passion. The guy says:
“Nastia, you’re a smart girl, multiply 315 by 12.
Of course I am smart...
Pause and Blessed Silence. It multiplied five minutes until it came to be separated. I was offended. The silence continued...

and Grazhdanin.
