"A fool, a fool, I see a fool in the forest,  a motley fool," "I am ambitious for a motley coat," and "Motley's the only wear."

Motley is of course the parti-colored garment worn  by Elizabethan court jesters.   And Fools were the happy fellows who were paid to entertain the king and queen with self-effacing humor that instructed as it amused. In fact,  Fools were really the only members of their  societies who could tell the truth to the King or Queen without having their heads lopped  off.  They had the freedom of speech that makes our own Constitution one look weak by comparison.
