A rogue alive to the ludicrous is still convertible.If that sense is lost, his fellow-men can do little for him.

-Emerson, RalphWaldo

There are even times when any assumption of dignity becomes ludicrous, and the traveller must, as Mungo Park once had to do,'lay down as a rule to make himself as useless and as insignificant as possible, as the only means of recovering his liberty'.

-Galton, Sir Francis
