A person who boasts himself hard to please because nobody tries to please him.
There is a land of pure delight,
Beyond the Jordan's flood,
Where saints, apparelled all in white,
Fling back the critic's mud.
And as he legs it through the skies,
His pelt a sable hue,
He sorrows sore to recognize
The missiles that he threw.
Orrin Goof
