When I was a kid, in backwoods West Virginia, my dad and uncles would always refer to people as “rich as Croesus”. I wondered then but never asked, “Who’s Croesus?” I didn’t learn who Croesus was until I was a teenager.
That would have been Cletus Croesus, who gotta a doublewide over yonder!
(((My neighbors in the Trailer Park think I must be rich as Croesus, since I don’t share my 750 sq ft single with anyone else but my Dawg.)))
