Local Newsman Mispronounced Plymouth BADLY!

I`ve jokingly called Plymouth, Ply-mouth back as far as when I was a kid.
This is the result of our absurd education system. People have really started butchering pronunciations. The latest one I've heard ruined is Potomac. One guy kept saying it as "pot-o-mac." I heard someone repeatedly say it as "p-atomic"
I think it was named after the Indian tribes that lived along it. They think it was actually pronounced as Pot-o-mac. It may of had an extra letter in it also. We`ve always pronounced it
Pa-tow-mic.
