No. 3: Don't drink Coke on (fill in the date)

There have always been stories of a kind stranger giving a tip to someone (usually an elderly lady) in line at a grocery store after she helps him pay his tab, but the "Don't Drink Coke" legend got a jolt of new life after 9/11.

This urban legend claims that Arabs working in a Coca-Cola factory have tainted the product to coincide with a certain date.

The email goes somewhat like this: "THIS IS TRUE or THIS REALLY HAPPENED! So and so's son works at Quickie Mart. There was an Arab man in line and he was $1 short for his groceries. An elderly woman gave him the dollar. He waited for her outside of the store and said 'You people don't do things like that for us so I'm going to do something nice for you.' He told her not to drink any Coke products on Sept. 11."

This particular version seems to have started in 2002. Coca Cola has received so many inquiries about it, they actually posted a response on their website.

Here's our response to this: Don't ever believe emails that say, "this really happened to me," or SHOUT IN UPPERCASE LETTERS: THIS IS A TRUE STORY!

No. 2: Free money, honey

There are more than a few of these emails that circulate around, tempting the reader to share in the wealth by "participating" in a company beta testing.

The promises of free cash, free cell phones, free trips to Walt Disney World, free computers and more are bogus, no matter how many emails you forward to friends and family.
