This one is nothing to do with window cleaning, but is quite true, so please indulge me....
Back in the 60's, when I was an apprentice electrician, one of my older colleagues, did a job in a lady's house which involved lifting upstairs floorboards.
The lady had a horrible Pekinese dog, just like "Tricky Woo" in the James Herriot stories, and the bl**dy thing kept trying to get down the hole where Bob was trying to thread a cable though.
In desperation, he slapped the dog on the snout and it promptly dropped down, dead!
Grabbing the poor animal, he laid it on the lady's bed, where it normally used to rest, and sure enough, the lady eventually brought Bob a cuppa and found the dog in the adjacent room.
Deep sorrow, (from the lady), with sackcloth and ashes all round, and Bob sympathising with the customer, and saying, "There, there, poor old *** died lying in his favourite place" Blah, blah!
