The body parts were all arguing about who should be in charge. The heart said: "I pump the blood that keeps us all alive. I should be the boss." The lungs said: "Without us sucking air, we'd all die." And so all the parts... the eyes, the ears, the hands all made their case. Finally the brain said: "I control all of you. That makes me the right choice. I make the decisions... so I'm the boss!"
While the parts were all considering the brain's strong argument, the asshole chimed in: "I'm the most important! I want to be the boss." Whereupon all the body parts laughed in his face.
So the asshole closed up. In a few days the heart pumped slower, it was harder to breathe, the eyes were watering, the hands were weak. Finally all the parts had to agree... the asshole could be in charge.
Which proves that you don't have to have brains to be the boss, you just have to be an asshole.
Little Johnny was on a park bench stuffing all of his Halloween candy in his mouth. An old lady walked up, saying: "Son, don't you know that eating all of that candy will rot your teeth, give you acne, and make you sick?"
"My grandfather lived to be 105 years old!" replied Johnny.
"Did he eat five candy bars at a sitting?" the old lady retorted.
"No," said Johnny, "but he minded his own freakin' business."
