From AWD Forum:

Everything has happened, but one case is remembered especially. January is the month of the unfortunate 98th year, Prague-Moscow flight. Among the last passengers on board is the famous psychotherapist Kashpirovsky. As late, he was rewarded with a voucher in the very tail, in the smoking salon (at the time, Aeroflot was still smoking). The plane takes off, the relaxed people drink beer, eat lunch - and smash in the tail with a slim tabun, smoke. In a few minutes, the smoke curtain. Irritated Kashpirovsky makes a comment to somebody: "Could you not smoke in my direction?", "What is the answer of a stifled neighbor: "And you smoke with your hands - smoke and dissolve." The curtain.
