HA HA, that's great!
No, I don't think I have.
But in hs, we had a teacher from Boston and he had said, "Park the car in the yard" like the first day, so he had to deal with us begging him every class to say it, which he would, chuckling.
I have a thing for imitating accents, and did that one so much it eventually leaked into mine. When some friends in the 90s once laughed at my derp-a-derp face telling me it was "Arthur Avenue, not Awwthuh" (what locals call Belmont), I realized I had to relearn pronouncing my "R's (I thought it was how everyone said it here). My name has two "R"s in it, and spelling it on the phone to whatever company was a doozy which I had to repeat, "...- a - aawhr - ..."
Even now when I spell it, it still sounds forced to compensate, like a stereotyped pirate "ARRRR"
