'Foo' 'Bar'???

Why is 'foo' and 'bar' always used as examples of variables and stuff in coding? I know it was a big word in Saving Private Ryan... Just wondering. :D

Thanks... that's a great link :D

I once asked the same question on a forum. That is why I know :D

Oh my god, how sad was that. I read the entire thing, and I cared so much. :(
