Despite what these people may think, the world does not revolve around them. How some of us get by in our daily lives believing we are the most important person in the world is beyond me, but these people don't seem to think twice before standing up at concerts, not returning their carts, and leaving restaurant booths worse off than they found them. 

While some of the items here are clearly jokes, like the guy going around turning odd people's TVs, some of them are as real as they get ( we're looking at you dude who took his shoes off on the train). 

What's worse than someone who doesn't care about other people? Nothing, there is nothing worse than someone who thinks the world revolves around them.
