Did you know that Shakespeare's 115th sonnet contains a hidden message? When the poem is formatted with the appropriate font and character spacing, as shown below, the underlined letters spell IT'S A SONNET BY W.S. The second sonnet is an anagram of Shakespeare's, and contains its own similarly-arranged message.
"It's a Sonnet (Not Sestina),"
