An 85 year old man 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 seperate suites so that the old fellow not 
over exert himself. After the 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 groom ready for action. They join 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 the old
guy is again ready for action. Somewhat surprised she consents to
further coupling which is again succesful after which the 
octogenarian bids her a fond good night and leaves. 
 
She is certainly ready for slumber at this point and is close to
sleep for the second time when there is another knock at the door 
and there he is again, fresh as a 25 year old and ready for more. 
Once again they do the horizontal boogie. 
 
As they are laying in afterglow the young bride says to him " I
am really impressed that a guy your age has enough juice to go 
for it three times. I've been with guys less than half your age 
who were only good for one." 

The old guy looks puzzled and turns to her and says, "was I already 
here?"
