After his annual checkup, Bob learns that he has a rare disease and 12 hours to live. His wife tearfully says, "Honey, I'm going to give you a night you'll never forget."
They make passionate love with an ardor they haven't felt in years. When they're done, Bob asks his wife, "Can we do it again?" This time it's even more passionate.
Later, as she is about to doze off, Bob gives her a nudge and says, "Honey, I know it's getting late, but I think we can do it one more time."
"That's easy for you to say," she complains. "You don't have to get up in the morning."
