So I was recently chillin in this map, hanging around the plaza for like.. 20 minutes, and then one of the payphones started ringing. I got curious because 1. It reminded me of that recent trend going on of people talking about how uncomfortable singleplayer gmod is, and 2. it's a ringing phone. So I walked over to one of the payphones and press 'E' on it. I thought it would be a DHMIS reference when I heard a click, but instead I heard a voice say "Seven Days." Now I don't know if this a very well known easter egg, but I still wanted to share it. Very spooky, made me shut down my game.
