There are some questions in the TF universe--questions like "Is Pyro a boy or a girl?" or "Who will be the tenth class?"--that get asked so often that they become, in a sense, unanswerable.
Then there are the questions nobody has thought to ask. Questions like, "Every time you explain something supernatural in TF2 you say the Soldier angered a magician. Who is the magician?" Questions like, "If the TF mercs went out trick or treating, what costumes would they wear?"
These are the questions we ask, because unlike those other questions, these ones we have an answer to. Answers like, "His name is Merasmus the Magician, and he's in a Halloween comic!" Answers like, "The TF mercs would wear awesome costumes that you can pick up by collecting scattered gifts in the Halloween update--which will be live very soon!"
