At 85 years of age, Morris, a very rich man, married Lou Anne, a lovely
and beautiful 26 year old.
Since her new husband is so old, Lou Anne decides that after their wedding
she and Morris should have separate bedrooms, because she is concerned
that her new but aged husband may overexert himself if they spend the
entire night together.
After the wedding festivities Lou Anne prepares herself for bed and the
expected “knock” on the door. Sure enough the knock comes, the door
opens and there is Morris, her 85 year old groom ready for action.
They unite as one…All goes well, Morris leaves his bride, and she
prepares to go to sleep.
After a few minutes, Lou Anne hears another knock on her bedroom door, and
it’s Morris. Again he is ready for more “action.”
Somewhat surprised, Lou Anne consents for more coupling. When the
newlyweds are done, Morris kisses his bride, bids her a fond goodnight and leaves.
She is set to go to sleep again, but, aha you guessed it - Morris is
back again, rapping on the door, and is as fresh as a 25-year-old, ready for
more “action.” And, once again they enjoy each other.
But as Morris gets set to leave again, his young bride says to him, “I
am thoroughly impressed that at your age you can perform so well and so
often. I have been with guys less than a third of your age who were only
good once.You are truly a great lover, Morris.”
Morris, somewhat embarrassed, turns to Lou Anne and says: “You mean I was
here already?”
The moral of the story: **Don’t be afraid of getting old…memory loss has its advantages! 
**
…very good one!
