I actually came up with slaying the dragon on my own when I was like 12. I cant believe people here caught on so fast. I guess I shouldn't be shocked. I used to do variations on the slaying the dragon thing, like I have to save my kingdom, I need to go save a princess, etc...
Any time I hear this, all I can think of is this: And if that's not bad enough, thinking of what her sisters could possibly look like is even more frightening.
