My Grade 8 teacher introduced the unit on Communism by telling us that, from now one, everyone is going to get the same grade. It'll be Cs for everyone. I was a smart ass, so I knew something was up and didn't take the bait, but a lot of the A students were pissed and screaming how it wasn't fair. The C and D students were all, "Sweet, now I don't have to do homework!"
Then she let it drop: "And that's how communism works..."
