Release the hounds

The Consumerist is taking votes for Worst American Company; the top vote-getters will presumably go into a runoff to pick the Worst of the Worst.

I have no dog in this particular hunt, though given the particular focus of the Consumerist site, and even though they didn't say so, I think they'd prefer to hear about firms with whom the voters have personal experience. (Just in case you were, say, going to tell all your friends at DU to write in "Halliburton".)
