A funny thing happened at work today. The most pompous of my colleagues — Oxbridge education, plummy accent — was giving a long and particularly tedious talk. Then he drew something on the blackboard. An impromptu map, I think, but at this stage I was no longer paying attention. He continued speaking but turned around repeatedly and added to the map. For each addition the picture began to look more and more like a penis. After a while there was no doubt. There it was: a perfectly formed manhood in all its fully erect glory. Testicles, pubic hair and everything. I began laughing. First a little snicker, than a louder guffaw. Heads were turning in my direction. I whispered my observation to the person next to me who made a face of disgust. How dared I! Not funny. Not funny at all.
