I love Gaelic names. There was an Irish woman on Big Brother a few years back named Caoimhe (pronounced: "Kee-vuh"), and naturally she became referred to by fans as "Daoimhe".

I've had a lot of run-ins with counterintuitive surnames of German origin in southern Indiana. I could pronounce them as German names just fine, but they Americanize the pronunciation juuuuust enough that it becomes a guessing game.
