Thanks everyone, it wasn't an important question, but I've been wondering for a while now, and just finally had to ask......so now I know, and I'll say 15 by 1, if I ever have to -- outloud.
BTW Macybaby, I've also wondered if the numbers mean something, so it's good to know I'm not the only one that doesn't know. I've got too much time on my hands if I think of strange things like this......
