... a limerick marathon? Suggested rules:
Risqué but not pornographic.

There was a young lady from Blighty
Who wore the most terrible nighty.
When her friend said ‘Why do it?'
She said ‘They see through it,
And that guarantees me twice nightly'.

haha, what is it with dynamite sticks

ok, slightly cruder

There once was a young man from Brighton
Who said to his girl, "You've a tight one"
She said, "Pardon dear soul,
But you're in the wrong hole.
There's plenty of room in the right one."

LOL

There once was a man from Peru
Who fell asleep in a canoe.
He dreamed of Venus,
And played with his penis,
And awoke with a handful of goo.

and another..

There was an old man name Toot
Who had warts all over his root.
He put acid on these,
and now when he pees,
He fingers his root like a flute.

A new member called Kwistofur Wobbin
Moaned so much that he was caught sobbing
His lisp was so profound
That every whinge was a sound
Whike a whittle boy wid no wackkers on the job in

There was a beautiful woman called Cleo
Who had a temporary set back because of an a hole
Being emotionally involved
She forgot her looks and personally would resolve
In a near future gondola romantic singing 'Hasta la mio'
