I realize that not everyone will be familiar with the Team Fortress 2... mythos? Can we call it a mythos? We probably shouldn't, so don't tell anyone. But whatever the fiction of this world is, I realize that not everyone will be aware of this stuff. But hopefully you've heard of the game. This comic from Valve can bring you up to speed, as well as deliver a shovel-full of humor right to your slack-jawed face.
No, I can't have Saxton Hale on the show. I considered it, but he sent me a letter threatening that he would stop being a fictional character long enough to deliver me "a beating devastating enough to make Ted Roosevelt put on a dress and cry himself to sleep". I think he was serious.
So, I won't be doing that.
