Along those lines:
A very elderly couple walked into the AA hall to attend their first meeting.
The sober men whisked the man into a corner to talk, while the sober women tended to the woman.
The sober men asked the drunk, "How long have you been drinking?" The drunk replied, "Fifty years." The sober men exclaimed, "You look remarkably well for drinking 50 years. What's the secret to your fine appearance? Do you and your wife still have intercourse?"
The drunk answered, "I don't know. Let me ask her."
And he yelled across the room, "Hey honey, do we still have intercourse?"
His wife yelled back, "How many times have I told you? We have Blue Cross Blue shield!"
