A 60ish woman went to the doctor for a 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 goes out in the waiting room and tells the husband that his 
wife needs to have sex three times a week. The 70 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 I 
play golf so she'll have to take the bus."
