In the blog post Famous Poems Rewritten as Limericks on LanguageHat.com (2 April 2018), a certain Trond Engen posted the following limerick:
The earth, like an orange, is blue.
Your love and your smile — yes, you do!
The window, the bee,
the sun, la-dee-dee…
I wish I were sure it was true.
He asked whether anyone knew this but nobody seems to have provided an answer. My own searches have led to nothing. Can anybody else do better?
