Before getting to the Black Friday GIF insanity, I think this experience from a retail worker on Reddit perfectly sums up everything that's horrible about the day: 

"Back in my poor college days when I worked at Walmart, we had a fight break out over a bike. Fists were thrown and there was some blood. Eventually, one guy got ahold of it and managed to get away from the crowd. He rode the bike out of the store to flee his pursuers (without paying)."
