Toby Young
Has been trying to delete his accumulated dung:
His Twitter account was a virtual Augean stable
And strongly offensive. I very much doubt he is able.

I've worked on a variant using animal names: critterhews.

Here's one:

The armadillo
Makes a terrible pillow.
Cold, hard and gray,
It keeps walking away.

[Roger Slater]

The lion
has a mouth big enough to put a guy in
and hence I think it would be sage
not to join it in its cage.

[John Isbell]

The zebra or zebra
is not lacking a single vertebra.
It is a backboned creature:
not Congress's defining feature.

[Roger Slater]

An Elegant Pig
if given a sprig
of parsley with his slop
will eat it non-stop.

[Roger Slater]

The owl
wears a scowl
without reason or basis.
It's just the way his face is.

[Matt Q]

Basking sharks
are drawn to sunny parks.
Why, you ask?
They love to bask.

A duck-billed platypus
once spat a "fuck"-filled splatter cuss
at God
for making him look so odd.
