25th Anniversary

On their way home after celebrating their 25th anniversary, she thanks him for a wonderful evening. "Oh. it's not over yet", says the husband. Once in the house, he gives her a little black velvet box. She opens it in anticipation, "But what are these two little pills?"

"Aspirin", says he.

"But I don't have a headache," she says.

"There you are, I told you the evening wasn't over yet!"
