A 65 year old woman is naked, jumping up and down on her bed laughing
and singing.  Her husband walks into the bedroom and sees her. He
watches her a while then says, "You look ridiculous!  What on earth do
you think you're doing?"

She says, "I just got my checkup and my doctor says I have the breasts
of an eighteen-year-old." She starts laughing and jumping again.

He says, "Yeah, right. And what did he say about your 65 year-old
ass?"

"Your name never came up..." she replied.
