An elderly woman went to the doctor for a check up.
After examining her and checking her cardiovascular activity,
the doctor recommended that she engage in sexual activity three times a week.
Embarrassed, the woman asked the doctor to tell her husband.
The doctor went out into the waiting room and told the husband
that his wife needed sex three times a week.
The elderly husband replied, "OK, Doc. Which days?
"Monday, Wednesday and Friday would be ideal," replied the doctor.
"Well, I can bring her on Monday and Wednesday," the husband said,
"but on Fridays, she'll have to take a taxi."
