Not to say that you would like to play one on someone, but just in case we have complied a few websites for you to use as you see fit.  How about forwarding this site so your friends can see their drivers license photo.  Or warn them about the dangers of dihydrogen monoxide.  Or you could send an outraged email  to your victim  about animal abuse and attach the Bonsai kitten website link.  Where, alledgedly, people can buy kits to stuff a small kitten into to have it grow into a small square shaped cat.  There are even more to choose from at this hoax website list, so pick a few victims and sit back and have fun.  Happy pranking!
