One time this Texan girl said to me "YEW SHAW DOO HA-AVE A PERRRDY AAAKSENT"

And I've got to tell my French-Canadian tale.
I was working as a customer support analyst and had ongoing dealings with a French-Canadian company. I was having great difficulty in making myself understood in English. After several frustrating phone calls I tried talking to them in my very poor "Schoolboy French". They immediately replied in perfect English.

We got on fine after that.
