Halo 2 Easter Egg - Grunty Initials

_MAJOR_ SPOILER ALERT

When playing as the Arbiter in single player mode for the first time (chasing down the heretic leader), you will enter an elevator plagued by Flood. Eventually on the walls in Flood guts there will be a J S on the wall, standing for Joseph Staten, the voice of the Grunt and one of the Bungie(The creators of Halo) team members.
