A famous author was autographing copies of his new novel in a Cleveland department store. One gentleman pleased him by bringing up not only his new book for signature, but reprint editions of his two previous ones, as well.
"My wife likes your stuff," he remarked apologetically. "I thought I'd give her these autographed copies for a birthday present."
"A surprise, eh?" hazarded the author.
"I'll say," agreed the customer. "She's expecting a Cadillac."
