A travelling salesman finds himself stranded in the tiniest town in Australia. He knocks on the door of a little hotel. "Sorry, we don't have a spare room," says the manager, "but you're welcome to share with a little red-headed schoolteacher, if that's okay."
"Oh, that'll be great," says the bloke, grinning from ear to ear. "And don't worry, I'll be a real gentleman."
"Just as well," says the manager. "So will the little red-headed schoolteacher."
