Happy Birthday to Cathy!

I wanted to send a belated birthday to my sister, CATHY, who, as of yesterday, is the exact same age as Fergie.
From now on, for no apparent reason, really: all ages will be correlated with Fergie years.
I myself am 5 years older than Fergie, making me *5* in Fergie years.
When I told my sister yesterday that she was *0* in Fergie years, she really didn't seem as excited as I was... I mean, *0*-- that's practically like starting over!
Anyhoo, Happy Birthday, Cathy-- I wish you and your lady lumps a very happy year! (yes, it's still stuck in my head; can you tell?)
