oh yeah that was on his brainstorming list of titles!. But keep in mind, he usually had a few of those ... not to consider using, necessarily, but because they were amusing to casually drop and perhaps amuse himself with some misdirection .
One of my favorites:
PS: I Hate Myself
And another:
15 Minutes of Shame
CAVEAT: these last 2 were on so many lists over so many years, its entirely possible --- actually, probably likely -- they were on WB & DF brainstorming lists
I think that was just a typical Walter joke, although with him you never know for sure!
