My friends went somehow to the lake, swim and have a good time. Upon leaving the city, they were stopped by a haishnik. Standard situation, verification of documents, but since the driver looked young, the haishnik thought that schoolchildren were sitting in the cabin and decided to check whether they were drinking alcohol. And in the salon, for a moment, there were four healthy foreheads, all completely bearded and like schoolchildren were very long ago. Despite this, the haishnik, looking into the salon, asks the question: "What class, boys?". And a loud voice from the salon replies: “Working.”
