All good stuff!
Here's my first contribution in Limerick form:
A good friend of mine who's no dimwit
Had a pinny and wanted to pimp it
He persuaded some lass
To sit nude on the glass
But she stuck to the thing like a limpet
With her arse still glued to the glass
He managed to fix this odd farce
Using fulcum and lever
He prized off her beaver
And her farts were heard in Madras
Sorry, but I have to say that has to be the absolutely worst limerick I have ever heard. F-
