Bill was super cool about this, too.
See,the number nine is my lucky number.
I'm not a believer in numerology or that stuff, but check this out:
If you add up the numbers of my birthdate and the year, then break 'em down....comes out to 36. 3+6=9.
Take my preferred name - Ed.... "E" is the fifth letter... "D" is the fourth... add 'em = 9
My initials... EFP.... 5...6...16 = 27... 2 + 7 = 9
Uh huh. There are other instances, but i won't bore ya.
Anyway, 999ED was just about perfect for your boy here.
Now, I have been told that the RV crowd might be interested in Mary Lou's number... 714RV. My UNLUCKY number i "7".
7+1+4+18+22=52. 5+2 = 7.

But, all is not lost.... Tack on the "n", and she becomes a "3'.... 66 = 6+6=12....1+2=3. Still.... inconsistant. If we have to count the "N", then we hafta do that on everything in the interest of consistancy. hmmmm...
HOWEVER:
Her serial number is 15079383. - - -
1+5+0+7+9+3+8+3=36.
3+6 = 9
She still loves me.
