Funny/weird things that happened in your game without you controlling it?

I dunno, my sims will run around San Myshuno or Sulani to the various social spots without me realizing it and do a bunch of random things. They also wear clothes that are not in the outfits I created for them. They create their own romantic, friendly, and rivalry relationships. They also woohoo on their own. Plus all of the normal stuff like make beverages, talk to each other, dance, paint, swim, work out, clean, read, play video games, etc. Nothing quite as dramatic as your story yet, at least not that I remember.
