Third Time's a Charm

So how about this, for the third quatrain of The Cleaning Lady:

I use a dustmop,
But never crouch,
So don't go looking
Beneath your couch.

Not inspired; it telegraphs the rhyme, and the joke is obvious the minute couch flashes upon the mental retina. But at least it doesn't change the subject, as the old lines did; and dustmop fits the falling sixth well enough. Serviceable.
