1 you know how todd always says "we dont want to spoil anything. well there should be a todd howard follower (like adoring fan) who gets knocked unconcience so we can beat him again and again. anyway if ur doing a quest u can ask him about what to do next in it. and he replies "i don't really want to spoil anything" (PUNCH) u can also tell him go jump off a cliff he spawns at closest cliff and jumps. its a fun stress reliver.
2 there can be a fat guy like tourretts guy and every time u walk past him he yells "OH PISS" you can make him follow u and if you run ahead of him he yells "WAIT A MINUTE U dike" if he shoots and misses (or screws up anything else) "BOB SAGAT"
i think it would be funny as hell
