AN: This is pure crack. I am not responsible for the state of your mental health after reading this. This is currently planned as a one-shot, but if there are enough interested readers, or more random plot bunnies that I could think of, I may continue this. So for now, sit back, relax and enjoy. 

AN2: This is really crackish, I cannot stress this enough. Oh, and comments are very much loved. Like very very very much loved.
