Once a doctor


*Nirbhau Nirvair*
Once a doctor went to a mental hospital. he was walking by a room and saw a guy holding his ear to the wall, so the doc went to that guy and pushed him aside and tried to listen so the doc put his ear against the wall and said i don't hear anything. that guy slaped the doctor and said i'm listening to this wall for 20 years i don't hear anything you just came and how the hell can you hear something.
