On a Southwest flight to Reno from SJC, the FA was serving a group of PAX sitting in 2 rows in front of me. They apparently knew each other because the teasing was non-stop between the FA and the passengers in front of me. Toward the end of the flight, the turbulence was so heavy that a few of the passengers were getting nervous. The FA took advantage of this and brought some empty plastic cups on a tray from the front of the plane toward the rear. He of course stopped at his friends row, and after the next big bump came along, the FA pretended to slip the tray from his hands, and dropped all the empty cups all over the PAX in front of my row. At first most of us thought the cups were full, but it immediately dawned on us that they were empty and it was a joke. There was continuous laughter for the remainder of the trip.
