What if the famous Dodo bird were found not to be extinct? Thousands may one day may be found to still survive on some hitherto unknown island near Mauritius? What would we do then? “Dead as a Dodo” or “to go the way of the Dodo” will be no more.
Raphus cucullatus will be thumbing their seriously huge bills at us – nah nah nah nah!
We will then have to find another seriously unlucky ex-species to use as a euphemism for “being gone for all money” – or dead.
Dead as a democracy perhaps?
