An older couple were lying in bed one night. The husband was falling asleep but the wife felt romantic and wanted to talk.

She said: "You use to hold my hand when we were courting."

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.

Thirty seconds later she said: "Then you use to bite my neck."

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

"Where are you going?" she asked.

"To get my teeth!!"
