I don't remember where or when I first encountered this and according to Snopes it has been around for some time, but I still think it is funny!
FYI, I saw the Goblet of Fire trailer a bit ago and I have this to say to everyone on the f-list who said it looked so good...:
You're totally right!!! It looks fanatastic!!!!! My biggest complaint is that Mad Eye Moody didn't look like I expected him to.
