In the 80's I worked with a guy who had a theory that most people who grew up with SQL in the early days pronounce it "sequel", and the younger generation was more used to saying it as the letters; S-Q-L.

At $PREVIOUSJOB I worked with a guy from Boston who pronounced "query" as "quarry". But he had a lot of bizarre pronunciations, so we just let it go. And not just because Boston, either.
