Surprise... Surprise...

At 85 years of age, a somewhat senile Morris marries Luanne, a lovely 25-year-old.
Because her new husband is so old, Luanne decides that on their wedding night, she and Morris should have separate bedrooms. The newlywed is concerned that her new husband may over exert himself if they spend the entire night together.
After the wedding festivities, Luanne prepares herself for bed, and for the expected “knock” on the door.
Sure enough, the knock comes, the door opens, and there is her 85-year-old groom, ready for action. They unite as one. All goes well, whereupon Morris takes leave of Luanne, and she prepares to go to sleep.
After a few minutes, Luanne hears another knock on her bedroom door.
It’s Morris! And he’s again ready for more action. Somewhat surprised, Luanne consents to further coupling. When the newlyweds are done, Morris kisses Luanne, bids her a fond good night, and leaves. Luanne is set to go to sleep again.
However, after a few short minutes, there is another knock at her door, andthere he is again… Morris, as fresh as a 25-year-old and ready for a bit more action. And again they enjoy one another.
As Morris is once again set to leave, the young bride says to him, “I am thoroughly impressed that at your age, honey, you have enough juice to go at it three times. I’ve been with guys less than a third your age who were only good once.
You’re a great lover, Morris!”
Morris, looking somewhat befuddled, turns to Luanne and says…
“WHAT?…You mean I was here already?!”
