I gave context (attribution) because Capote's quip dates from the late 1950s, and it seemed likely few people today have heard it or know the context. Capote's criticism of Kerouac seems funny and relevant (to me, anyway) without the context. Whether one thinks Capote got it right about Kerouac, or just liked to stir up shit to polish his own image, makes no difference to the humor. The irony comes from me using the quote not to criticize Kerouac, or any actual human writer, as Capote originally intended.
