This is one of numerous hoax messages that promise various things if you spread them. The message itself looks like this:

Hi. My name is Jeffrey Newieb I am a marketing analyst for M & Ms chocolate candies based in Hershey, Pennsylvania. As the year 2000 approaches, we want to be the candy of the
millenium. As you may already know, the Roman numeral for Y2K is MM. We are asking you to pass on this e-mail to 5 friends. Our tracking device is calculating how many e-mails you send out. Every time it reaches 2000 people, you will receive a free case (100 individual 55 gram packs) of delicious M & M candies. That means the more people it reaches, the more candy you're going to get. Mmmmmm... yummy M & Ms for the year 2000!!.
