I don't the get the appeal with jigsaw puzzles*. When I was growing up, my family would go through phases of doing puzzles. There would be a card table set up with a puzzle on it. It would take days to finish it.
I just don't see what satisfaction you get from it.
Since I hated doing puzzles I would sometimes hide the last piece. Then, when it was almost completed and my sisters were looking under the couch for the missing piece I'd sneak in and put the last piece in, "...AND DONE!"
Now THAT'S satisfaction.
(And look at that guy in the picture. I bet he's a jigsaw puzzle show off. "I've been doing jigsaw puzzles for 63 years. When I was a kid, they were simply called Jigs. You would get your shoes fixed at the Cobbler and then go next door to the Jiggy - your local Jig supplier and pick up the latest Jig. Of course they were much harder back then and the edges were sharp so you needed skill. Not like today's jigs".)
*I do like Sudoku but that doesn't really count.
