I got it from this month's Reader's Digest.
My friend's mother told me about the two women who had moved in next door.
"I can't understand why there's no man in the house," she said.
A week later, she decided to clear things up.
"Hello, Jean," she said, leaning over the garden fence. "I hope you don't mind my asking, but are you and Lisa leprechauns?"
She came back into the house and announced, "Well, she said no, and that's good enough for me."
