Milkshake Sonnet

My milkshake is a peanut-butter treat
With chocolate, too, appearing in the mix
A glass so large, so sickeningly sweet
That I need less than half to get my fix

I'm in a diner with a weighty tome
Great English Poems, edited by Briggs
Across the table, Adam looks at home
With Murakami, and with coffee swigs

There comes a sudden motion from below
As Adam lays a tickle on my knee
I counter-jest, exclaiming, "Nandato!"
Which Adam laughs at oh-so-heartily

It's Wednesday. We have nothing much to do.
The skies change from a rainy gray to blue.
