Dear manufacturers of subway cars, when you test the air conditioners (and you clearly test the cars on pigs because there are always livestock carriages) - put on pigs and put a thermometer in your ass to finally understand that your condoms don't work and if you wear something warmer than winds (in winter, for example, unexpectedly, right?) Then the testers will float on top of it, and the windows will not be opened.
