"who will be the boss"

"who will be the boss".

Brain said: I will be the boss, I think for you all.
No, said the hart. I pump the blood, I will be the boss.
Lungs: we give the air for you all... we will be the boss.
And everybody want to be boss, even legs (bring you evrywhere) intestine (feed you).
but finally... ass said: I will be the boss.
ha ha ha said all organs, you the boss? No way.
But ass make angry, and sfinkter make no pass.
Intestine stopped. Hard start beating. Legs start trembelling. Brain hurt from the pain...

Finally, all of them said: please, stop it. Ok, you are the boss.

what we could conclude from the story?
You should not be the brain to be the boss.
