Well if we're digressing from folk/trad then:
Whale kipper whelkome in the hillside
I believe in mackerels
Prawn to be wild
Buddy can you spare a lime
Go mango
They tried to sell us egg foo yung
Absinthe makes the heart grow fondue
Pudding on my top hat

And back to trad: Sorbet, sorbet (geddit?)

Stop, stop, stop. My brain hurts.
