A Hull girl I was dating a lot of years ago went to study at Bradford Uni and found it very difficult to order a glass of "Coke" in the local pubs there. The bar staff all thought she wanted a sample from the Captain of the USS Enterprise.
I was listening to Radio 2, again, a good while back, and they were interviewing BBC local Radio station producers and,on this particular day, they were talking to a lady called Liz Meech. I thought I knew the name and it turned out she was working at Radio Humberside at the time. It was asked of her what a Hull accent sounded like, as she was a Mancunian, and she said that "If you ask someone from Hull what the capital of Japan is they'll say "Terkeyo"..."
I was outraged initially but the more I thought about it, the more I realised she was correct!
