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 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 used 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!"
