An old couple is having breakfast when the old woman says to her husband, "Just think, honey, we've been married for 50 years.?"
"Yes," he replies. "Fifty years ago we were sitting here at this breakfast table together. And we were probably naked as jaybirds."
"Well," the old woman snickers, "should we get naked again for old time's sake?"
So they strip off their clothing and sit back down at the table. "You know," the old woman says breathlessly, "my nipples are as hot for you today as they were 50 years ago."
"I'm not surprised," replies the old man. "One's in your coffee and the other's in your oatmeal!"
