A "do it yourself" catalog firm received the following letter from one of its
customers: "I built a birdhouse according to your stupid plans, and not only is it
much too big, it keeps blowing out of the tree. Signed, Unhappy. The firm replied:
"Dear Unhappy, We're sorry about the mix-up. We accidentally sent you a sailboat
blueprint. But if you think you are unhappy, you should read the letter from the guy who
came in last in the yacht club regatta."
