In my book,limericks should be a bawdy 5 line verse. I.E.
There was a young man from Bangkok,
Who got his tool caught in a rock,He pulled it to hard
And stretched it a yard,
Now the women hang round in a flock.
There was a young lass from Devizes,
Whose boobs were of two different sizes,
One was so small
'twas no good at all,
The other won twenty first prizes.
