I once saw a guy with a very old lawn mower, that thing was ye old push sort, and it was clearly on its last legs. He had ONE Strip left to do, and you know how people hate to leave that one strip in their yards. It's roaring , sputtering, choking, and roaring again... I'm walking by, noise loud! But he makes slooow progress.. and gets to that last square of long grass! Just after that, that rusty mower finally shuts down. The man looks at it, checks the grass, and rather than complaining, looks at the lawn mower and says "that'll do, pig, that'll do."
