I think they deposit them into a Nigerian bank account

Remember that kid who would get his life-saving dialysis only if everyone sent their soda can pull tabs to their cousin's friend's office manager? It seems the campaign was so successful in America that he made a full recovery and is now traveling the world spreading alchemical medical procedures.

In our office, there is a print-out on the bulletin board announcing the good news that our PET bottle tops can now become smiling cartoon vaccines for sad cartoon teddy bears. It shows a complicated chart with a suspiciously cyclical part in the middle explaining how the screw tops become are converted at a rate of 800 to 1 into "vaccine" (which, incidentally and irrelevantly, is pronounced "waksheen" in Japanese), and then pleads that you "do now what you can do now. Save a life."

The three pages have been posted in English and Japanese and worked over with green highlighter, so it is obviously true.

Someone at the office has valiantly carved a milk carton into a receptacle, thereby performing two acts of planet-saving heroism in one selfless stroke.

Coincidentally, this was posted a few weeks after rules were changed to require PET bottles to
be recycled with the plastic labels and lids removed and - oh, but this is another topic - put into the burnable garbage.
