Keeping on a theme -- if you would, gentle reader, speak aloud the team name up there in the title.
Done? Ok, thanks.
For my entire life, I pronounced the word "fahl-cons." Last year, in a bar, I said that -- and it was greeted with peals of laughter and calls for me to say it again. Apparently, everyone else says it "faal-cons." (for a better approximation, go here and press the pronunciation links: Merriam-Webster says both are ok, though faal-cons seems preferred.)
Since then, it's been a mild obsession of mine, conducting unofficial surveys of how people say it and where they're from. My parents, who presumably taught me how to speak, say it "faal." In fact, the only people I've found that agree with me are as follows: the Elk (raised in Minnesota), Fidel (raised in London), and my little brother (raised in Colorado).
I've also been told that "fahl" might be acceptable if you're being some hoity-toity snob and discussing things like "Falcon Crest," but it's not acceptable for the Atlanta Faal-cons.
