So we've established that Festivus is a celebration for lonely loners and hateful hatemongers, but where did it come from? Well, it pains me to tell you this children, but Festivus was created by Santa Claus. Yes, I am talking about the very same Santa Claus that you think leaves presents for you every Christmas. That's a stupid thing to think, and I guess you must be stupid to think that, huh? We all know Jesus is the one who leaves those fantastic presents, usually alcohol or underwear.
