Something there is that doesn't love a wall,
That sends the frozen-ground-swell under it,
And spills the upper boulders in the sun,
And makes gaps even two can pass abreast.
(...) Robert Frost MENDING WALL

Stupidity can beget irony.

Frost's "Good fences make good neighbors" is put into the mouth of a grumpy dolt who's imagination can't exceed his father's cliches. This famous poem's meaning is that fences make for bad neighbors.
