One of the ones that used to bug me--portrait. In the city I used to live in, there was this photo finishing place that ran ads on TV for their "portrait service". Now, I have always pronounced and heard it pronounced as "POOR-trit" According to the dictionary, there is also a correct pronunciation that sounds more like "POOR-trait" (note that the emphasis stays on that first syllable?). This fellow, however, pronounced it "poor-TRAIT" about seven times in thirty seconds.
On pronunciations of place names that might want to make your head explode--not too terribly far from where I live, there are towns named Cairo and Vienna--KAY-ro (like the corn syrup brand) and VIE-an-na (like vie and the name Anna put together), respectively.
