A lady comes home from her doctor's

A lady comes home from her doctor's appointment grinning from ear to ear. Her husband asks, "Why are you so happy?" 

The wife says, "The doctor told me that for a forty-five year old woman, I have the breasts of a eighteen year old." "Oh yeah?" quipped her husband, 

"What did he say about your forty-five year old ass?" She said, "Your name never came up in the conversation."
