It's hard to think how I normally pronounce it, when I'm trying to pronounce it. Ya know? LOL

I know one pronounciation that is definately incorrect is Datsun ... like the car. That always kills me when people call my grooming shop and say, "I need to get my Datsun in." I am ever so tempted to say, "For an oil change?"
