True story, not sure if if counts as humour but I thought it was pretty funny. I was flying from Sri Lanka to Malaysia on an aisle seat with my wife across the aisle when a Saudi couple sat next to me. The Saudi women (who was wearing a full face burka) sat next to me then the guy, then they swapped places because I think they did not like that arrangement. Anyhow, once they realised I was with my wife, they were pretty friendly (and they spoke good English) and started showing me their holiday photos on their laptop. Here the funny thing:
The wife was not in any of the photos - guess there is no point if you just wear a full face Burkha all the time.
