Death Preparation Joke

Barry and Hannah, an
old married couple,  are sitting on the couch watching TV. On the show
they were speaking about how to prepare in case of death etc. “Honey,”
says Barry, turning to his wife with a serious expression, “I want you
to promise me, that if there ever comes a time that I am dependent on
just machines and bottled fluid, that you will make sure to  put an end
to it.” “No problem hun,” said Hannah, and she promptly got up, turned
off the TV, and poured his beer down the drain.
