Bush to Miers: “P.S. No more public scatology”

P.S. No more public scatology

This has to be the most bizarre in-joke I’ve ever seen. An actual letter from Bush to Miers (barely legible handwriting notwithstanding) ended with a strange postscript — P.S. No more public scatology. For those unaware, scatology is an obsession with excrement or excretory functions.
Media sources seem baffled as well, with most reports pointing out a warmer than usual relationship between the two:

U.S. Supreme Court nominee Harriet Miers told George W. Bush in a 1997 birthday card that he was “the best governor ever” and, in a separate note to her boss, said she hoped his twin daughters recognize their parents are “cool.”

I’m not sure if that warmth is coming from a steaming pile of poo or something else, but from now on I’m replacing the phrase “taking the Browns to the Super Bowl” with “nominating Harriet Miers to the Supreme Court.”
Update: Some of you are saying this could be a Bushism for eschatology (the branch of theology that is concerned with the end of the world). Because you know, Bush is like the special kid with the helmet according to some of you.
If Miers is indeed a doom-and-gloomer fundie, that alone could flush her nomination with more moderate Republicans.
