Variations on themes

I've always liked the short poem "This is Just to Say" by Williams Carlos Williams. Kenneth Koch parodied the poem in "Variations on a Theme by William Carlos Williams."

The Art of Poetry MOOC led by Robert Pinsky this week looked at Kidding and Tribute, and it inspired me to write a variation of my own...

Variation on a Theme by Kenneth Koch

I found the poem you wrote
and left on the table
which you probably meant to send to your publisher

I put my own name on it
and mailed it out
So much better than anything I could ever write
