There is a heavily Irish-decorated bar on the north side of Chicago, hidden away from all the trendy restaurants and stores. On Saint Patrick's Day of every year, this bar will suddenly turn pitch black rather than the usual green. If you open the front door of the bar, you will be faced with utter darkness. Even if it's broad daylight outside, none of the light spreads into this bar. If you step inside, you can hear a jukebox playing a broken record, over and over and over... "I see a red door and I want it painted black... No colors anymore, just want it to turn black..." If you turn back around to walk out, you'll find that the door isn't there anymore. Just more darkness.
