I asked C.H Greenblatt the question "What's Kratz and Claire's last name?". He answered with "Kratz’s last name is revealed in “The Unknown Comic” I believe. Or somewhere around there. I can’t remember exactly. In my head it was always Kratz Kristofferson. But that’s not what it ended up being. And I don’t think we ever gave Claire a last name."

So, originally, Kratz's last name was orginally Kristofferson.
