At 85 years of age, Morris married 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 over-exert 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 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. 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?" 
Alzheimers - it has its advantages.
