United States: A flyer sent out to thousands of potential customers by a Texan party supplies store contained an unfortunate error:

An ad for Party City was supposed to highlight a sale on Hanukkah items, but it also contained a hateful anti-Semitic message.

The advertisement includes the sentence CC Hates the Jews in large, bold letters.

'CC' is apparently the initials of an employee at a design company who changed the text when the layout artist was otherwise engaged. Clue (MacOS 10.2.4): Apple -> System Preferences -> Screen Effects -> Activation. See the bit that says 'Password to use when waking the screen effect'? Click the radio button marked 'Use my user account password'. MacOS 9 also allows you to specify a password to exit the screen saver.
