Tossing away your keys

Remember that promise you made me? That you'd be good and then I'd unlock you? It doesn't matter how sneaky you are, I'll always find out what you've been up to. Well naughty subs don't get treats, naughty subs get punished. Don't think I don't know when you're playing to be punished, thing is if you play stupid games you win stupid prizes and if you're going to be stupid then I guess you won't be needing your keys back.
