There are too many too count, but it's all in good fun.
Of the top of my head, there's
The Gentleman's Club, for precious little boys
The Dirty Furkids Club, for those that don't like baths
The Crazy Club, for those who dress their babies
The Spoiled Rotten Club, self-explanatory
SSLS, a secret as far as I know
The Pick-on-Brendon club, just to be mean to my hubby cause it's fun
I know I've missed some, but I'm sure others will post them!
