NSFW - This trivia is considered "Not Safe for Work" - Click to Reveal
During any crime that involves you entering someone's room (i.e. Domestic Dispute), after arresting the perpetrator, go into their bathroom. If the toilet seat is up, you can find a smiling face made out of feces. If you shoot at the toilet enough, there is a chance it may gush out dirty water as it's damaged, and if you look again, that smile will have turned into a frown.
