I have just discovered, via J Budziszewski's blog, that Thomas Aquinas wrote a near-limerick. It goes like this:

Sit vitiorum meorum evacuatio,
Concupiscentiae et libidinis exterminatio,
Caritatis et patientiae,
Humilitatis et obedientiae,
Omniumque virtutum augmentatio.

The scansion requires the vigorous use of a shoehorn with both hands, but the rhyming is good. It translates as:

May [the sacrifice] purify me from sin,
do away with my evil desires and passions,
bring me charity and patience,
humility and obedience,
and strengthen me in all virtue.

I couldn't resist, sorry Raak. Haven't looked in here in ages and work is really boring at the mo. I've proofread 300 pages of 700 so far and it's dull dull dull, so a bit of rhyme and meaning wrangling will do me good.
May the sacrifice cleanse me of sin,
Chuck libido and lust in the bin
And instead I would be
More goodY-goodY
And purer, both outside and in.
