Do You Call the Number Zero "O"?

[Cbsteffen]

Some people do it because they're too lazy or too anxious to say zero. I know a lot of radio stations at more than 100.9 mHz call the station "One-o..." (For example, "One-o-one point five" instead of "One hundred and one point five" for 101.5). I used to think that sounded neat. Now I think it's stupid.
