A man believed that he was dead. He was healthy, but he told everyone that he was dead. His family and friends could not convince him that he was not dead.
Finally, his family convinced him to see a psychiatrist.
“You are dead?” asked the psychiatrist.
“Yes,” said the man.
“Do dead people bleed?” asked the psychiatrist.
“No,” said the man, “dead people do not bleed.”
“Are you sure?” asked the psychiatrist.
“Yes, I am sure,” said the man. “Dead people do not bleed.”
The psychiatrist quickly grabbed the man’s right hand and jabbed his forefinger with a pin. Immediately, his forefinger started to bleed. The man looked at his bleeding finger in horror.
“Oh my God!” he said. “Dead people DO bleed.”
