Extra credit for those who mispronounce Carnegie Mellon. It's Car-NAY-gee, not CARN-a-gee.
I remember when I was accepted to W&M - my parents were so thrilled that it was a college, not a university. Well, also that it was a full ride!
The only other examples I can think is how many people confuse Stamford, Stanford, and almost any other school that starts with ST. Sorry that I'm not more help.
