Be careful criticizing pronunciation -
- it's not grammar, and while there are standard English pronunciations, I personally LOVE the different pronunciations you can here from all over the country . "Car Talk" wouldn't be the same without that distinctive Boston accent, I can't imagine my grandmother without her soft southern drawl, and even Palin's almost Canadian-clipped speech is interesting to me.
That said - NUCLEAR. There are some weird pronunciations of that out there!
