Mulla Nasruddin and one of his friends had been drinking all evening in a bar. The friend finally passed out and fell to the floor. The Mulla called a doctor who rushed him to a hospital.
When he came to, the doctor asked him, ‘Do you see any pink elephants or little green men?’
‘No,’ groaned the patient.
‘No snakes or alligators?’ the doctor asked.
‘No,’ the drunk said.
‘Then just sleep it off. You will be all right in the morning,’ said the doctor.
But Mulla Nasruddin was worried.
‘Look, doctor,’ he said, ‘that boy is in bad shape. He said he could not see any of them animals and you and I know the room is full of them.’
