Each poster comes up with the next line, whoever finishes the limerick starts the next one. There once was a man who felt blue
Sorry, Packard, but you've got the meter for limericks wrong. Fixing it, it would start: >>There once was a Captain named Kirk<< Who threw himself into his work
(I could debate that for weeks, after working for two years on a research project on lyrical meter, but I daresay that would make this a Red Room thread. You've never seen a true partisan until you watched Skulaceva arguing with empirical metricists.)
