F.E.A.R. Easter Egg - Cheesy Poofs

In interval 4 (Watchers) right after the fight with the two stealth soliders you find a rather..large man well when he finally lets you inside wait around and look on the ground you'll notice that there are two cheesy poof bags on the ground the reference...South Park and the fat man may also be a possible reference to Cartman since he will lean up against the opening to the door and eat cheesy poofs, you may have to hit you're headlight to see this
