One Turbot says to the other "do you believe in Cod?"
The other replies " I think we each know a Sole". "I believe one day when the chips are down and we are at our most battered we will each know a Plaice and we are destined to fillet".
They exchanged a glance and swam away.... just for the Halibut.

I hope my Whiting doesn't offend. Remember believers.... believe in Cod and one day you will be Prawn again.
