What rhymes with drains

Washing up the supper things
- stewed gigot chop, some fish,
new potatoes, carrots and peas,
if you must -
at the bit where glasses 'n plates
lead on to a few pots
a poem came to mind, line by line;
that will do, I thought.
So neat it went down the drain
before I even pulled the plug.
Maybe it will surface, somewhere,
sometime. Though it won't cause
ripples
