Parts of the body are having a debate. One day all the body parts are gathered together to discuss who amongst them should be the leader.
The brain steps forward and says "I should be the leader for I am the cleverest. I keep everyone organised and find solutions to problems".
Everyone is quite impressed until the heart steps forward and says "I should be the leader for I am the most important and vital organ. I supply the blood and keep everyone moving. Let us also not forget that a person can survive brain death but not the lack of a heart".
The debate keeps on until a mysterious figure emerges. It's the sphincter.
He says "Howdy. I reckon y'all ought to let me be the leader".
Before he could carry on his pitch the rest of the body parts were already laughing and jeering at his ridiculous proposal. So, the sphincter stormed off and shut down.
Within a week the waste had built up causing problems for everyone including the heart and brain, until finally they relented and let sphincter be the leader.
The moral of the story is. To be a leader you don't have to be smart or important, just an arsehole.
