While having a salad and Brooklyn beer for a late lunch, and later waiting to board, there were some crazy announcements from the speakers. 

At one point a Japanese airline cautioned passengers to visit the toilets before boarding X-flight to Tokyo, because they anticipated the Fasten Seatbelts light would remain on the first 5 hours (!!) of the flight.  

An Aeroflot flight kept threatening "this is the final boarding call" interspersed with increasingly plaintive requests for three (apparently very important) passangers to please please please report to the gate. The "final boarding" period dragged on for about an hour. I hope they were sitting in first, else there may have been a revolution in the very narrow aisles of cattle class.
