We were travelling from the office to the seaside on board the company train. I was introduced to the new sales director who told me “I actually have a pretty great sense of humour.” I guffawed in his face.

“Simply by saying that you have proved you have NO sense of humour and are – in fact – a KNOB”.

I then stamped around the train carriage shouting “Knob, Knob, Knob” at the top of my voice.
