I have been using that to depict Billy Krystol. On election night my wife said that he reminded her of a foul snarling and hissing possum. So I found the picture and posted it whenever someone who post one of his inane war suggestions essays. Miss Marple and I have had this ongoing labeling of him as a snarling hissing possum for a long time.
Then I like to use it to depict those who snarl at us or GW as we try to do our jobs. Not smart to stand in the middle of a road and snarl at Express Buses!
