An elderly couple was lying in bed one night. The husband was falling asleep but the wife was feeling romantic and was eager to talk.
“You used to hold my hand when we were courting,” she said coyly.
Wearily he reached across, held her hand for a second and 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.
Shortly afterwards she said: “Then you used to bite my neck.”
Angrily, he threw back the bedclothes and climbed out of bed.
“Where are you going?” she asked.
“To get my teeth!”
