Oh... where to start...
1. "If you're an asshole and you know it, don't say anything!"
2. "What's that over there?"
3. "Oh, you're looking for the key to the Door of Doom? I know exactly where it is! Follow Me!" and then get killed in the stupidest way possible.
4. "Why, Cloud, I see you insist on carrying around a huge sword that is bigger then your body. Could you possibly be compensating for a small package?" and then laugh, because in FF you can't kill NPCs.
5. Just follow them around, chanting, "Hail the Conquering Hero!"
6. "Why yes, I am a seven foot tall Viking warrior with biceps the size of watermelons and a sword the size of a BMW. However, I am far too lazy to kill twenty Banglefaced Bunny Rabbits myself, so could you go out and do it for me? I'm late for my daily oiling."
7. Spread rumors about the allegedly great stuff my neighbor has hidden in his house.
all of that, or just mumble something about needing coffee and then give you a pokeball tutorial.
