Pretty printing

So, when I came back from dinner Friday night to begin my long evening of debugging, I saw the following text on my whiteboard:

When the pretty printer receives
a PP_UGLY flag it fails

Later, this conversation took place when a coworker stopped by. (Useful information: Phil is a coworker of small stature who has an odd sense of humor.)

Alex: Hmmm, that looks like Phil's work.
Me: Why do you say that?
Alex: Because it looks like the kind of dumbass thing he would think was funny.
Me: Oh. I thought because it was low to the ground.
Alex: Good. Now, if you never tell him what I just said, I'll never tell him what you just said.

And then he left.
