No more public WHAT?

First off, hat tip to the Smoking Gun and Nick at Hit & Run.

Now, to the WTF moment of the day. George Bush writes this to Harriet Miers:

No more public scatology? Is he promising not to do it himself, or instructing her not to do so?

Scatology, for those of you who don't know, is

1. The study of fecal excrement, as in medicine, paleontology, or
biology.

or

2. An obsession with excrement or excretory functions.
The psychiatric study of such an obsession.

And is it okay for whichever one of them does this sort of thing, to do so in private, but not in public?
