My favorite so far .... I think my favorites were last weekend, where they were asking you to go to various websites, find the "Search" button and plug in the number "1" and then copy the URL to whatever page it took you to. The next day they put up about 12,000 hits asking you to do the same thing with the number "2". It didn't take a long time once you got into a routine, and you were directed to websites all around the world, which was pretty interesting. You even got to figure out how to read the word "Search" in Polish, Portugese, French, Chinese, Dutch ..... it was very interesting for me.
