Barry returned from a doctor's visit one day and told his wife Carol
That the doctor said he only had 24 hours to live.  Wiping away her tears,
he
asked her to make love with him. Of course she agreed and  they made
passionate love.
 
Six hours later, Barry went to her again, and said, "Darling, now I only
have 18 hours left to live. Maybe we could make love again?"  Carol agreed
and again they made love.

Later, Barry was getting into bed when he realized he now had only eight
hours of life left.  He touched Carol 's shoulder and said, "Darling?

Please?  Just one more time before I die?"  She agreed, and then
afterwards she rolled over and fell asleep
Barry, however, lay there awake and listened to the clock ticking in his
head, tossing and turning until he was down to only four more hours.
 
He tapped his wife on the shoulder to wake her up.  "Darling, I only
have four hours left! Could we...?"
 
His wife sat up abruptly, turned to him and said, "Listen, I'm not
trying to be funny, Barry, but I have to get up in the morning - you
don't......"
