You can never go back

There was this couple who had been married for 50 years. They were
sitting at the breakfast table that morning when the old gentleman said to his wife,
“Just think, honey, we’ve been married for 50 years.”
“Yeah,” she replied, “Fifty years ago this very day, we were sitting here at this breakfast table together.”
“Hmmm,” the old man said, “We were probably sitting here naked as jaybirds fifty years ago this morning.”
“Well,” Granny snickered, “What do you say…should we?” Where upon the two stripped
to the buff and sat down at the table.
“You know, honey,” the little old lady breathlessly replied, “My nipples are as hot for you now as they were fifty years ago.”

“I wouldn’t be surprised,” replied Gramps. “One’s in your coffee and the other one’s in
your oatmeal!”
