Here's the actual limerick:
There was a young man from place B
Who satisfied Predicate P,
He performed action A,
In adjective way,
Resulting in Consequence C.
There was a young man of St Bees,
Who was stung on the arm by a wasp,
When asked "does it hurt?"
He replied, "Yes it does,
but I'm sure glad it wasn't a hornet.
There was a young man from Japan,
Whose limericks just wouldn't scan,
When he was asked why,
He said in reply,
"I'm not really sure but I think it might be because I always try to cram as many words into the last line as I possibly can".
There was a young man from Tyree,
Whose limericks stopped at line three,
A bit like this one.
There was a young man from Peru,
Whose limericks stopped at line two.
There was a young man from Verdun.
And then, of course, there's the one about the Emperor Nero.
Whilst I'm on this topic, if anyone knows where it is possible to get hold of a copy of The Oxford Book of Meta Limericks by Elliott Moreton and Carl Muckenhoupt, please let me know (I've tried abebooks, and amazon, which about exhausts my online book sources).
Update (21/05): a selection of poems from the book are available here, which just makes me want it more.... :(
I really love the 'copyright' one.
