Halo 3 "legendary Legendary" ending?

[well?]

of course we all know about the "Legendary ending" of Halo 3 that shows an extra few seconds and the ship heading towards some sort of planet-like structure. I've heard something about a third different ending that can be seen after you beat the last level with all of the skulls on. Before my brother and I even attempt this, I would like to know if anyone has heard anything about this. You can imagine how impossible that'd be with Blind, Iron, Black Eye, etc...

i herd this too a long time ago and checked it out and there is no "third ending"

 

[Avenged Disturbia]

It's a myth.

Even if there is a "third ending" you're better off seeing it somewhere else than enduring the waste that would be your existence if you even attempted Legendary with every skull.
