The term "jaywalking" was coined by city people when country people moved to the cities, because country people didn't know how to cross the streets. It just so happened that country people were called "jays".
The world is round. There is a group people who think its flat and promoting that fact (Flat Earth Society).
The guy sounds like a nut.
'...when satellite images showed Earth as a sphere, the society was undaunted; Shenton remarked: "It's easy to see how a photograph like that could fool the untrained eye."'
Hmm... Well if we consider the theory that we may be inside a black hole, and the "laws" of physics are "remade" to work in the (extreme conditions of the )black hole, then it is possible that what we think we are seeing as "round" is in fact "flat".
In my own two pence, the word "grot" is a word that was actually created backwards! In the Beatles movie "Hard Day's Night", George Harrison refers to something as "dead grotty". When asked to clarify, he says, "you know, grotesque." This started everyone using the word "grotty". Following common English logic, noun + y = adjective, so "grotty" was assumed by a large amount of people to come from the root word "grot", which is, while uncommon, still used.
