Do you still have intercourse?

An eighty-three year old lady, Barbara, finished her annual physical
examination, whereupon the doctor said, "You are in fine shape for
your age, but tell me, do you still have intercourse?"

"Just a minute. I'll have to ask my husband," Babs said.

She went out to the reception room and asked her husband,
"Tony, do we still have intercourse?"

Tony answered her impatiently, "If I told you once, I've told you
a thousand times... We have Blue Cross!"
