[Martin Parker]

And, supporting Jerome's efforts at waving the flag for Devon poets, how about ....

A red-headed king shot by Tyrrell,
who maybe had thought him a squirrel,
would not have been dead
if he'd gone north instead
and hunted for game in the Wirral.

OR --

A right Norman bastard from France
led Saxon King Harold a dance.
But a poke in the eye
was the chief reason why
the latter died looking askance.

OR -- Though, sadly, I do not think Onan was a biblical aristo but merely a nephew of Technicolour Dreamcoat Joseph.

Since Onan had fiddled around
and spilt all his seed on the ground
it's unpleasant to guess
at the state and the mess
of the crop which the harvesters found.

Or even --

Once Onan had fiddled around
and spilt all his seed on the ground,
of which nomenclature
of strangely formed nature
was the crop that the harvesters found?

Enough from me, I say! This could become a thread of record length and ingenuity.
