What’s the best unexpected moment in your game?

At the moment I can only really think of the time I played late at night a little "juiced". The next day when I loaded up the game, I had my sim visit his girlfriend. She had a baby apparently. Confused, I checked out who the father was using NRaas: MC and it said my sim was the father. They had never woohooed at this point so my only conclusion is, don't drink & sim? :D
