"An 86-year-old UK man who spent eight years working on a massive jigsaw puzzle has been horrified to discover a single piece is missing.
After scouring the house to find the piece, Mr Harris's family contacted the puzzle company to try and obtain a spare, only to be told the jigsaw had been taken out of production.
The family fear the missing piece has been thrown away by mistake or eaten by one of Mr Harris's pet dogs." source
LOL - this is hilarious... although I do feel VERY VERY sorry for this poor man!
