Haven't heard that for a while. Sweet, HHH! Maybe you should work on the follow up revenge poem where the offending fish gets caught and made into a fish finger? But then, seeing as you are now a confirmed veggie (and I am already), I shouldn't be encouraging that sort of behaviour.
One, two, three, four, five,
Once I caught a fish alive.
Six, seven, eight, nine, ten,
I wouldn't let it go again.
Why didn't I let it go?
'Cos I was feeling hungry so.
How did I cook the fish?
As a finger, my favourite dish.
