We got a political questionnaire in the mail several years ago. This presumably went out to every household in the state. Across the front of the envelope, in HUGE font, were the words, "YOU'RE 2005 POLITICAL QUESTIONNAIRE IS ENCLOSED!"
Now, I'm not the type to point out every mistake that I see, because I am sure that I make a few of my own, but this was a statewide thing put together by a professional survey firm.
*le sigh*
