The Dog Returns To His Vomit

As it will be in the future, it was at the birth of Man
There are only four things certain since Social Progress began.
That the Dog returns to his Vomit and the Sow returns to her Mire,
And the burnt Fool's bandaged finger goes wabbling back to the Fire.*

And a convicted bank robber returns to the scene of the crime, and commits it again.
