My choice is paper. Think about. How would you start a fire without paper? And there never would have been newspapers, books, comics or porno magazines without paper.
Then there's rocks. Rocks suck. I mean, what can you do with a rock? Hit stuff? Throw it at things? Ever get one in your shoe? Besides, rocks just lie there and look stupid when you aren't hitting stuff or throwing them at things.
Scissors you say. Forget about it. I mean, they are just plain trouble. Have you ever fell running with scissors? That's a stupid question, of course not, because you'd be dead if you fell running with scissors and wouldn't be reading this. And if you didn't die, your mom would have whooped your ass for running with them. Scissors are just plain trouble. So I say stay away from scissors.
Oh yeah, I forgot toilet paper. Now where would we be without toilet paper? You know where? All smelly and with a rash on our ass, that's where. Paper rules.
Which one do you choose?
