A man went to a party and drank some of the punch. Late for another appointment, he then left early. Everyone else at the party who drank the punch subsequently died of poisoning.
Why did the man not die?
1.the punch had some sort of poison (semi obvious) but the man's appointment was for the doctors and he got a shot for the poison or somehow got it out.
2. i got this answer from looking at the title. the man was death and he poisoned the punch by drinking it. the appointment was to kill someone else.
