Am I the only one who as as kid heard people talking about “Youth-In-Asia” and wondered how you signed up for a study year abroad?
Our school does a “Word of the Day” for the daily bulletin, which is read over the intercom 3rd period. If I am feeling frisky (since I write the list of said words) I’ll drop in something like “ennui.” 
I am easily amused.
In 3rd grade, we were reading a Ramona Quimby book by Beverely Clearly. Ramona has a doll that she named Chevrolet, after her father’s car. I was reading aloud and read it Chev-Ro-Lay, like the car. My 3rd grade teacher snidely told me it was Chev-Ro-LET. Being the relatively easy-going child I was, I shrugged and pronounced it the way she said to.
Until I was reading with a teacher’s aid and said Chev-Ro-Let and was snidely told it is Chev-Ro-LAY.
This was the same teacher who literally abolished half the class in the spelling bee because she pronounced “sure” as “shore” and they couldn’t understand her.
A british woman I worked with corrected my pronunciation prah-leen and told me it is pray-leen. WTF? I learned it from the MP Crunchy Frog sketch.
Oh, I saw sign in a antique car collector’s office, “Chickens live in a coop,” presuably for people who mispronounce coupe.
Come away ma cherie in my chevrolet coupe[/Bluto as The Continental]
Ah, yes. Elementary school. My third-grade teacher corrected me in front of everybody, as we were lined up to go into the classroom. Apparently I had some sort of accent that made ‘math’ come out ‘myath’. (Funny. I’ve never been to New Jersey!) She mocked me loudly in front of everyone. Needless to say, I corrected my pronunciation.
This same teacher was reading a story about some sort of forest animal. One night the animal saw ‘two firey suns’ approaching. The teacher became quite angry that no one in the class knew what the ‘two firey suns’ were. She was practically shouting. She finally revealed that they were the headlights of an approaching car. I almost protested, ‘Mrs. Gordon? We’re only eight years old. We don’t drive cars!’ (I still remember the exact words I thought.) But since she was so angry, I decided to keep my mouth shut.
In second grade the teacher was an elderly woman. I know all adults look old to kids, but Mrs. Bell really was. She was reading a story that had a character in it named Dud, obviously short for Dudley. She pronounced it ‘dude’ (or ‘dood’, if you prefer). I wanted to correct her, but the way I was brought up that wouldn’t have been polite.
In first grade we were in a reading circle. The texts said, ‘He had a cold.’ Kenny said ‘He has a colour.’ I wondered why Mrs. Barton didn’t correct him.
