A couple had been married for 50 years. They were sitting at the breakfast table one morning when the wife says, "Just think, fifty years ago we were sitting here at this breakfast table together." "I know," the old man said, "We were probably sitting here naked as jaybirds fifty years ago." "Well," Granny snickered, "Let's relive some old times." Whereupon 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 today as they were fifty years ago."
"I wouldn't be surprised," replied Gramps. "One's in your tea and the other is in your porridge."
