With bowler hat & tape measure in hand, the Boffins silently engage passers by to assess just who measures up to their expectations of how things should be. Very important things, such as the size of a trouser turn-up (which should be 2.5”) or the distance from elbow to wrist.
Areas of speciality include Childrens Entertainers. If a photograph is required, the Boffins are happy to oblige, providing everyone stands at the precise distance of 8.5” from the person next to them!
