       | Benjamin Tissoires response is pretty awesome in style, tone,
       | context, usefulness for both the layman and the expert. Kudos to

       | days.

       | stench, checked the whole feckin room and then I realised my hand
       | stinks. The very last thing I checked was the bloody Wacom tablet
       | pen that she got from us in the morning."
