My vote goes to Bonsai Kitten as I'm still getting outraged mail railing against this site, but seeing as it's April Fools day, what are everyone's votes for the best net pranks this year?
Kittens for Sale! This twisted, yet somewhat humorous site is a PRANK by MIT students. Yet the FBI doesn't think so. They are taking it serious. One would think that catching all the pedophiles online would be a bit more important then a hoax internet site.
