Norbit operates on the principle that vulgarity is automatically funny. Crassness doesn't need a joke attached because it is (in and of itself) the height of hilarity.
A harmless hilarity and a buoyant cheerfulness are not infrequent concomitants of genius; and we are never more deceived than when we mistake gravity for greatness , solemnity for science , and pomposity for erudition.Charles Caleb Colton
His hilarity was like a scream from a crevasse.
I knew that I would speak in the language of the vanquished No more durable than old customs, family rituals, Christmas tinsel, and once a year the hilarity of carols.czesław miłosz
Fan the sinking flame of hilarity with the wing of friendship; and pass the rosy wine.charles dickens
