The puzzle took most of the day
But we completed it
Just putting pieces slowly in
Completing bit by bit
And when we thought the thing was done
We had a shock in store
Because when all was said and done
It turned out there was more
The puzzle shifted all its parts
And left the middle free
With pieces that would fill it in
Incredible to see
We finished it again, this time
Completed it for real
For hours spent, the fun we had
Turned out to be a deal!
