Here’s my latest attempt at poetic rhyme subversion.
I worry so for dear old Bill,
So long abed, so very ill,
For if old Bill does not get well,
Then he will die and go too soon
To tell the tale he came to tell
And sing out his appointed tune.
Does it work? Although it does rely on the old comic cliché of “Hey, betcha thought I was gonna cuss!”, I think it still manages to be a poem rather than a mere gag.
