A man went into his doctor's room.
“I want you to give me the medicine to make me clever,” the man told his doctor. His doctor agreed to do it.
A week later. the man came back. “Still don't feel clever.” he said.
“Keep taking this medicine, come back next week, and you will become clever,” said the doctor.
“I still don't feel clever, are you playing a joke on me?” the man said the next time he came, “Do you really have this kind of medicine?”
“Now you're clever.” said the doctor.
