2.3.11 Who dies at the end of the "All I Want Is You" video?
{MJS} This question truly is frequently asked. I think it's the woman.
{DAC} I believe it is the midget who is in love with her. Earlier in the video he threw himself off the high trapeze swing, and when we see him at the funeral, it is really his ghost, and only his friend the strong man even senses that he is there. Then he throws in the ring, to be buried along with himself.
{CG} One widely accepted interpretation is that what's being buried on the funeral is the love from the midget for the woman - Thus he throws the ring in the grave. This also explains that "flying" camera effect - that's the midget's love leaving him.
