is that you must have no sense of fear." At this point, the lecturer sticks
his finger into the dead man's anus, and then licks it. He asks all the students

silence, they follow suit.
"The second thing is that you must have an acute sense of observation:
I stuck my middle finger into the corpse's anus, but I licked my index."
