A field guide to corpses

there was a professor at a school that taught morticians how to do their thing during an autopsy. The professor had a pretty slack bunch of students this time and decided to give them a test while they were around the corpse they had to practice on. he told them that to tell in the field how long a corpse had been dead without using any medical instruments all you had to do was insert your finger into its asshole which he did on the test corpse, several people gagged, one puked. He left it in there a few seconds then pulled it out and showed it to them. he then said you had to judge by the warmth you felt inside along with the taste and he stuck his finger in his mouth and sucked on it. More students puked of course. He then told them to do the procedure that he had done on the corpse for practice and reluctantly each one slowly shuffled by, stuck their finger in its ass and then into their mouth. once they had all finished he told them that another important thing about doing an autopsy on a dead person was observation. For example, if they had been paying attention theyd have noticed that it was his index finger he stuck in the corpses ass while it was his middle finger he stuck in his mouth.
