2123?

That works if 567 is 57, but I'm not quite sure why it's 567.

I've got a stupid one that I heard the other day...

What happened on November 27, 2003 that will never, ever happen again?
 
like with the November 27, 2003
had this even a previous occurrence? or is this an isolated thing?
my little brother had been 18 for 22 days... does that count.

oh i know... it was November 27, 2003... that will never happen again.

by the way, i'm not finding anything in the news about it either...

Arrange the numerals "123456789" to form a 9-digit number (referred to as "ABCDEFGHI") whose 2-digit subsets meet the following criteria:

1) AB is divisible by 2
2) BC is divisible by 3
3) CD is divisible by 4
4) DE is divisible by 5
5) EF is divisible by 6
6) FG is divisible by 7
7) GH is divisible by 8
8) HI is divisible by 9

There are two solutions.
I just saw this one... I think 781254963 works.
