I can't help but think I've read this somewhere before. Except with DOOM PATROL instead of ANIMAL MAN.
It was first written in an online article I read some time ago, and I thought it was pretty witty. The guy that wrote it also was not a big fan of Grant Morrison.
Also, thank you for the correction: it was Paul Kupperberg that wrote DOOM PATROL (another comic written by Morrison), not ANIMAL MAN. I actually feel a little guilty about that; Kupperberg's Krypton miniseries was fairly interesting.
