An older couple who are in their 60s were lying in bed one night. The husband was falling asleep … but the wife was in a romantic mood and wanted to talk.

She said: “You used to hold my hand … when we were courting.”

Wearily, he reached across, held her hand for a second, then tried to get back to sleep.

A few moments later she said: “Then you used to kiss me.”

Mildly irritated … he reached across, gave her a peck on the cheek and settled down to sleep.

Thirty seconds later she said: “Then you used to bite my neck.”

Angrily, he threw back the sheets and got out of bed.

“Where are you going?” she asked.

“To get my teeth …!”
