old-age after 70 (very funny)

An older couple was lying in bed one night.
The husband was falling a sleep, 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..!!!"
