Far be it for me to dampen anybody's creative enthusiasm, but Emm stated she wanted a limerick which is defined as :
A limerick is a five-line poem written with one couplet and one triplet. If a couplet is a two-line rhymed poem, then a triplet would be a three-line rhymed poem. The rhyme pattern is a a b b a with lines 1, 2 and 5 containing 3 beats and rhyming, and lines 3 and 4 having two beats and rhyming (from here)
So, it would be something along the lines of :
There was a young lady from Kew
Who was given a puzzle to do
She wailed and she cried
But her brains she had fried
And all for the sake of Sudoku
Obviously
not the winning entry, but it serves as an example (somewhat).
