The lovely thing about Italian is that once you know the rules, you can't help but pronounce a word correctly, with the possible exception of the accentuation of the syllables. I have a huge list of hated mispronunciations accumulating (of course I can only think of three right now).

My "favourite" bastardizations of Italian words:
bruschetta - "broo-shetta", should be "broo-sketta"
espresso - "ekspresso", should be "espresso" (Where's the X?)
Ross Rebagliati - "reb-lee-ati" should be "Re-bal-yati" (as close as I can spell it - there is no "gli" sound in English) (That's the Canadian snowboarder from the Nagano olympics who got in trouble for having pot in his system.)

Argh! Is all I can say...
