Recced because: I can't remember how I stumbled upon this little gem but I am extremely grateful that I did. It combines four separate universes into one so amazingly, I can't believe that it isn't canon. AnneHedonia manages to keep the the characters voice, attitudes and actions intact, which leads to much hilarity. Watch for the appearance of the companions/offsiders of the four main characters because that is so how this bizarre situation would go down.
For those concerned, you need not be a fan of all the other shows, such as House or the Mentalist, to get the gist of what is going on but if you have watched all four shows, you are in for a treat!
