Grazor: Mom told the story
by AlonZo: Valia
Grazor: When she was a little girl, her company, where she now works, invented a gas machine. The machine determined who was in front of him - a man or a woman, and, accordingly, poured a gasoline of red or yellow. He was standing on VDNC, GREAT queues were gathering, the machine was making a profit, but no one could understand how it worked.
AlonZo: I am afraid to think
Grazor: And everything turned out to be very simple: at the time women wore only shirts, not pants, not jeans. He photographed his legs below his knees and determined whether a man was in his pants or not.
AlonZo: It is genius :D
