I've had a friends club for my teen sim called "teens only, fools" (bonus points if you get the reference). It was basically a way for my sim to keep track of his friend group (though it's kinda sad cause I made him immortal using mods, so all his friends age up without him). I also made a similar club for my child sim, but all of her friends aged up at their first club meeting. I've also made a "do my housework" club which has cleaning objects as a club activity. I summon them whenever I need free housekeeping. And last but not least, the cult. Yep. They all wear those grim reaper robes and have club activities such as singing, meditating, and making speeches.
