I noticed he carefully left out Michigan/North Ohio/Indiana English which is consequently ranked as one of the most accurate and clearly understandable dialects of English in the world.
That is because my wife was standing right behind me while I was typing. She was born in Ohio, and grew up in Michigan. Her parents are from Indiana. I didn't want to risk offending the love of my life, especially when she woke up with a headache this morning. I don't want to make her angry!

Now my brother, man, he married a Newfie girl a coupe of years ago.

I was the best man at his wedding, back in my home town, which he still lives in. After the ceremony and pictures, we had 2 hours to kill before the reception. All of her family ended up back at my brother and now sister-in-law's place. Normally, I would have drove 5 mins up the road to my parents house to be with my relatives, but as part of the wedding party, I felt obligated to stay with the bride and groom. So, there I was in a living room with about 20 Newfies who were having 44 different conversations in 18 different directions at 240 word per minute! I was like
I had to just quietly slip out for some fresh air. My brother noticed and slipped out a few minutes later to laugh at me. He had been around Newfs for 2 years by then, he was used to it. I had been around my sure of Newfs, but never that many in one place at one time! Nicest folks in the world, without question, but you just can't understand half of what they are saying, even though you are supposedly speaking the same language
