Like cellar door, jism or flange: one of those words that rolls so sweetly off the tongue that you say it again and again and again, up until the moment when you introduce yourself as "Mr David Hysterectomy" to the drama teacher, and she runs out of the room.
Girls cry at anything!

We had a maths teacher Mrs.W who had a Hysterectomy, and for some ungodly reason, decided to tell her students. When she was on duty in the lunch hall, there would often be a spate of coughing. As in "Harruph-terectomy". This was, as the above has stated, very entertaining, until you see a middle aged lady standing in a room full of silenced, staring children, as she sobs tears, but is too upset to realise that she probably should leave the room. Some sense of duty forbid her from leaving the hall till her duty replacement turned up!
