A Soviet joke

A group of friends stays in a hotel in Soviet Russia. One of them ended up in a separate room and is trying to fall asleep. His friends, however, are loudly talking and telling each other political jokes in the next room. So he decides to prank them a bit. Calls downstairs, orders some coffee to their room and knocks on the door. Then goes: guys, are you crazy telling all these political jokes??? KGB is listening! They are laughing, making fun of his fears. Ok, he goes, let me show you! So he picks up an ashtray and speaks into it: “Major, can you please order some coffee to our room?” A minute later the coffee he ordered previously is delivered… Silence in the room, now terrified friends immediately go to sleep. He goes to his room and, after a good laugh, happily falls asleep. The next morning he goes to their room to tell them it was all a joke… but nobody’s there! He goes downstairs to make an inquiry and a lady replies: - Unfortunately, KGB officers took them away at night… He’s in shock, then regains his composure and suspiciously asks: - Wait a minute, if that’s the case, why didn’t they take me?! -Apparently the major loved your prank!
