A 75-year-old woman went to the doctor for an annual checkup. The doctor told her she needed more activity and recommended sex three times a week.

She said to the doctor, "Please, tell my husband."

The doctor went out into the waiting room and told the husband that his wife needs to have sex three times a week.

The 80-year-old husband replied, "Which days?"

The doctor answered, "How about Monday, Wednesday and Friday."

The husband said, "I can bring her Monday and Wednesday, but on Fridays she'll have to take the bus."
