You can check out Mad Kane's Limerick here, and see what her readers wrote. I'm not really much of a Limerick guy, but here's my offering.
A man who reported the news
His producer's direction refused.
"Suit and tie must I wear,
But for comfort down there,
Feets can only take ratty old shoes!"
Not great, but not too bad. I know Limericks are generally risque, but sometimes it's enough to get the rhythm and cadence.
