The good ol' days

A couple of elderly RVers who'd recently celebrated their 50th wedding anniversary were sitting on the sofa in their Airstream motorhome, 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 toward the rear of the motorhome.

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