One of the emails read:

    This is a chain letter which I received from Peter Baumbach a little while
    ago.  I know that all of you don't know me, but if you don't then you probably
    know Bill "Wadd" Waddington, who was here helping me think of names to whom
    to send this.  This letter is the infamous ARPA-net chain letter which
    caused much havoc a few years ago on the ARPA-net.  I think that it's pretty
    dead by now, but I just can't help but to send it along.
