Ode to a Burger and Fries

The challenge from www.poetryexpress.org/: Write a poem of 4 to 9 lines containing the words "mustard," "piano," "elastic," "moat," "notorious."

With a moat of mustard surrounding pickles,
the ubiquitous burger lies
there next to its notorious companion;
the oil saturated french fries.

In the ritual lunch, my pearly white teeth
like ivory piano keys stand
ready to bite into heaven, but alas —
texture and taste — elastic band.
