This is how it works - first 5 people to make a post (anything, just to bookmark their place) then edit in 1 line of a limerick once they've checked their place in the sequence. Without referring back to others, in case they've finished before you.
Lines 1 2 & 5 to rhyme with 'an'. Lines 3 & 4 can be freeform. Not too filthy please. Might be funny - probably won't be. What's the worst that can happen?
