At work yesterday and there's a young lad who works with me, ( doing loft conversions, ps it's the boss's grandson ) and he fell through the ceiling, well one leg did we had put new floor joist down but not new flooring yet, and we had some off-cuts left over and placed them on the floor too walk on but they spanned 3 joist with a few inches to spare ( 5 ) he only stood on the 5 inch bit and fell through the plaster board ceiling i wouldn't mind if it was where the stair well is going, but it was in the living room everyone saw the funny side of it ( thank fook ) lol
