Annual Checkup

A man arrived home from work one day and found his wife alone in the kitchen in a great mood, dancing and singing.
“What has you in such a happy mood today?” he asked.
“I had my check up today, she explained, “and my doctor said I have the breasts of an eighteen year old.”
“Really,” the husband replied, “and what did he have to say about your fifty year old ass?”
“Actually,” she said, “your name never came up!”
