On glurgy chain letters: In high school I was briefly on an email list to allow students from a certain theater program to keep in touch. I was disappointed to see that almost all of the emails on this list were forwarded rhymes, cheesy stories, and ASCII pictures of flowers, with the requisite warnings to pass this joy on to all my friends or face an agonizing death. I put up with this for a few months, then decided to do something about it. I sent a chain letter to the list, the only one I've ever sent. Its subject line was "The chain letter to end all chain letters," and its content explained that anyone who forwarded it would thereafter be exempt from all penalties threatened by subsequent chain letters, and would automatically receive their promised rewards, without forwarding any of them. It was both a satire of chain letters in general, and a mechanism to discourage superstitious/compulsive people from forwarding future glurge that came their way. (Unfortunately it didn't work for the friend who originally sent it to me -- she started sending me chain letters again a week or two later.) Technically it was a chain letter itself, but I felt the time had come to fight fire with fire.
As soon as I'd sent it, however, a boy responded to the list angrily. He was angry because he hated chain letters, and I had sent one. He ranted for a while, and then ultimately implored the people of the list not to send any more chain letters. The stream of forwarded stories and poems continued unabated, and he never commented on the subject again. My conclusion: Some people believe that emails which are not labelled "chain letter" are not chain letters, and so should be tolerated, while emails which are labelled "chain letter" are chain letters of the worst kind, and should outrage us all. I've also noticed that many people think "pyramid scheme" means "email with the subject line 'this is a pyramid scheme'". It's pretty lame.
