Disgustingly Hillarious

In response to Carly's essay on selfishness and the ability to easily make an enormous difference in somebody's life, I would like to share this video:

It highlights that while it is alright to be selfish sometimes, if it is taken too far, disaster can occur. I do not mean that if you don't tip your waiter, that you will end up in a safe, but rather that if you repeatedly act selfishly, eventually there will be a time when you need another's help, and it will not be offered because of your past transgressions.
