Doctor is gonna get killed today

In a mental hospital, a patient (mad) was after the doctor holding a knife in his hand. Doctor was running here and there and the mad patient was following him. The doctor went all round the hospital and everybody was saying that the mad person is gonna kill the doctor.
Guards were unable to catch the mad patient. Doctor was running through the corridor and came to the dead end. Doctor was so scared. The mad person marched towards the doctor slowly raising his hand with knife.

He was a feet far from the Doctor and the mad patient said, “Finally I got you. I’m tired now. You take the knife and come after me!”
