I would say AX 2002 was the worst ever AMV contest... oh wait, you said worst AMV ever contest. hehehe.
Well here is my entry:
1. Open up Window's media player.
2. Watch it for 2 hours.
3. The End.
Here is the stats of the video:
Anime: Various (All the scenes of total black screen I can find)
Music: I forgot what it's called but it's the song that all it is, is silence, and the music is all the strange little noises people make in the room.
I could actually make this video, but it would have the same outcome as the steps above, and I don't have hosting anyways.
