May I give you some context for Blind Freddy and the coal cellar.
Blind Freddy is a person who is as thick as a post, not the brightest spanner in the tool kit, not the sharpest knife in the drawer. You get the drift, this bloke was a world class under-achiever. The chap would have had a hard time finding his own bum if you gave him a route map and a compass.
Blind Freddy is said to be based on an English toff, a baronet named Sir William Pottinger who was sent from London to Australia's colonial goldfields to catch a bushranger, Ben Hall. It is not known if Sir Bill was really stupid or if it was just a case of a city bloke sent to catch a bushranger in unmapped bush that Ben Hall was born in. In any event it is said that Ben Hall could be on one side of a tree and Blind Freddy on the other and Ben Hall could smoke a pipe with no fear of capture.
The coal cellar is a reference to the darkest place possible. A coal cellar at midnight with no moon and a blackout is the most utterly dark place that I could imagine.
So the stage is set. We have the dim witted Blind Freddy blundering about in the stygian darkness of the coal cellar yet even he can see the absolute clarity of the statement made by Cuchuflete that you had agreed with and to which I was supplying a concomitant compliment.
Is that clearer?
