Barry and Hannah

Barry and Hanna, 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.

"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 honey," said Hannah, and she promptly got up, turned off the TV, and poured his beer down the drain.
