A couple who'd been married for over 50 years was sitting on the sofa, when the wife said, "Dear, do you remember how you used to sit close to me?"

He moved over and sat close to her.

"Dear," she continued, "Do you remember how you used to hold me tight?"

He reached over and held her tight.
 
"And," she went on, "Do you remember how you used to hug me and kiss me and nibble on my ear?"

With that, her husband got up and started to walk out of the room.

"Where are you going?"  she asked.
 
"Well," answered the husband, "I have to get my teeth."
