Quality Mnemonic

I needed to remember the number 837401573 and one of my [male!] friends suggested:

I want to have 8 children by the time I'm 37, but for this to happen, my husband will need a [good!] 401K. 4 plus 1 equals 5, and hopefully by the time I'm 73 (the reverse of 37), I'll be done having children.

This is priceless because it repeatedly cracks me up, plus I don't think I'll ever be able to forget this number. What a friend, Jack!
