Morticia reads Pugsley The Raven as a bedtime story. The Raven was a poem by Edgar Allen Poe, first published on January 29, 1845 in the New York Evening Mirror.
This is the part of the poem she reads to him:
"Once upon a midnight dreary, while I pondered, weak and weary,
Over many a quaint and curious volume of forgotten lore,
While I nodded, nearly napping, suddenly there came a tapping,
As of someone gently rapping, rapping at my chamber door."
