This couplet is from the Asses of Parnassus tumblr site, 6th February 2019.
“Success!” he toasted. Though I wished him dead
I smiled and raised my glass: “Suck cess!” I said.
About the use of form in this poem: the point of the poem is a lighthearted pun, therefore the shorter the poem the better – all you want is the setup and the punchline. Although a long poem in iambic pentameter gets heavy in tone, a single couplet can feel rapid, light and natural. Cheers! 🙂
