A thirtyish woman is jumping up and down on the bed and singing happily.
Her husband watches her for a while and then says, "Do you have any idea
how ridiculous you look? What's the matter with you?"
The woman continues to bounce. "I don't care," she says. "I just got
back from the doctor's and he says I have the breasts of an 18-year-old
girl."
"Oh really?" says the husband. "And what did he say about your 30-year-old
arse?"
"I'm sorry," says the woman, "but your name didn't come up."
