At age 85, Morris marries a lovely 25-year-old woman. Because her new husband is so old, the woman decides that on their wedding night they should have separate bedrooms. She is concerned that the old fellow could overexert himself.
After the wedding festivities she prepares herself for bed and for the knock on the door she is expecting. Sure enough, the knock comes and there is her 85-year-old groom ready for action. They unite in conjugal union and all goes well, whereupon he takes his leave of her and she prepares to go to sleep for the night.
After a few minutes there's a knock on the door and there old Morris is again ready for more action. Somewhat surprised, she consents to further coupling, which is again successful. The octogenarian once again bids her a fond good night and leaves. She is certainly ready for slumber at this point, and after a few more minutes, is close to sleep.
But, for the third time, there's a knock at the door and there he is again, fresh as a 25-year-old and ready for more. Again they ravish one another.
As they're basking in the afterglow, the young bride says to him, "I am thoroughly impressed that, at your age, you have enough energy to go at it three times. I've been with guys less than half your age who were only good for one time. You're a great lover, Morris."
Morris, looking quite confused, turns to her and asks, "You mean I was here already?"
