Pyramid Song and Mario Brothers Fan Animation?

UPDATED: In what is certainly one of the more bizarre things we’ve been sent, it appears that a clip of Pyramid Song pops up in part three of the Mario Brothers flash saga. I’m at a loss on how to describe these, other than to say that the official description is “a simple sprite animation depicting the tragic story of Mario and his ultimate downfall” and that they are not saying that in an ironic way.
See for yourself here– the Radiohead song is about a minute in. Should you wish, Part One and Part Two are also online.
(Thanks to Rob, who can corroborate that I am not making this up.)
