At 85 years of age, Morris marries Lou Anne, a lovely 25 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 takes leave of 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 action.
Somewhat surprised, but nonetheless willing, Lou Anne consents to more
conjugal bliss.

When the love-birds are done, Morris kisses his bride, bids her a fond
goodnight and leaves. She is set to go to sleep again, but Morris is back
again, rapping on the door, as fresh as a 25-year old. Ready for more
passion. Once again, they enjoy one another. But as Morris prepares 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?"
