Rock, Paper, wait, what...?

Well, exCUUUUUSE me for not understanding the power hierarchy of rock, paper, scissors! I never played it when I was little; I only started knowing of it a few years ago, so I can never keep straight how it goes. I (apparently falsely) assumed that everything beats scissors because ....oh wait a minute...scissors cut paper. and a rock smashes paper and scissors? is that right? Anyway, I have to think about it, and then people laugh at me, so screw them.
