I do that too--pick up accented pronunciations. I try not to, even though I *like* ad-VER-tis-ment better than ad-ver-TISE-ment. For instance.

It annoys me when Spanish (or whatever language) names are said wrong. Like Versailles Ohio. Versails. BER-lin New Hampshire. But on the other hand, you look like an idiot pronouncing them "right."
