A Medical Issue

The minister’s absence was explained as a “medical issue.”
He sat in the morgue, waiting for the coroner to find a body similar to his for substitution.
“What about DNA?” asked the coroner.
The minister rolled up his sleeve. “Take blood from me now, compare it to itself when they bring you the body back.”
The coroner nodded, took a needle from the supply closet and swabbed the minister’s arm.
The minister smiled, and then his strange face went slack.
The new minister entered the room, patted the coroner on the shoulder.
“Poisoned needle?” he said.
The coroner destroyed it.
