Once upon a time..

The heart, liver, stomach and rectum all had an arguement as to which was the most important to the body. The heart stated how important everyone knew it was. The heart said "I shall stop and you will see how important I am". The liver expounded on how no body could live without it and it would shut down proving it's importance to the body. The stomach did the same. They all looked at the rectum and said it was not as important as them. The rectum then simply said "I shall shut down and show you how important I am". The rectum promptly shut down and the body gradually completely backed up and the body died.
