Falling asleep in summits

Apparently summits have a tendency to last too long, speakers to talk too much and listeners to doze off from time to time. The last hours are usually extremely hard for both sides and this is the best moment for paparazzi and scandal hunters to get their funny images. Here you can see some of those photos. I wonder if anyone fell asleep during the Cuban President Fidel Castro’s speech of 32 hours 21 minutes and 15 seconds?
