A 75 year old woman went to the doctor for a check-up. 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 goes out in the waiting room and tells the husband that his wife
needs to have sex three times a week.

The 80 year old husband replies: "Which days?"

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

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