I'd be grateful for more movers and shakers in the limericks game please - to set good examples of rhyming and scansion to those perhaps less accustomed to the sound and feel of a good limerick, and perhaps also to show Marc that there are other subjects apart from sex to be limericked, and repeated references tend to make people drift away from the game.
