You've all seen those annoying legal disclaimers some companies automatically add to the end of all emails sent out from their systems? Some are longer than the actual messages... Here's one you might consider adding yourself, though it does break netiquette for sig length.
IMPORTANT: This email is intended for the use of the individual addressee(s) named above and may contain information that is confidential privileged or unsuitable for overly sensitive persons with low self-esteem, no sense of humor, or irrational religious beliefs. If you are not the intended recipient, any dissemination, distribution or copying of this email is not authorized (either explicitly or implicitly) and constitutes an irritating social faux pas. Unless the word absquatulation has been used in its correct context somewhere other than in this warning, it does not have any legal or grammatical use and may be ignored. No animals were harmed in the transmission of this email, although the pit bull next door is living on borrowed time, let me tell you.
Those of you with an overwhelming fear of the unknown will be gratified to learn that there is no hidden message revealed by reading this warning backwards, so just ignore that Alert Notice from Microsoft. However, by pouring a complete circle of salt around yourself and your computer you can ensure that no harm befalls you and your pets. If you have received this email in error, please add some nutmeg and egg whites, whisk and place in a warm oven for 40 minutes.
