An older couple 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!”
