Ugly Americans gets a even uglier when Mark Lily is bitten by a Bat-Boy and transforms into a creature resembling Steve Buscemi. The milquetoast social worker decides to use his singular power to loudly shriek to help clean up New York as Bat Person! The episode also features parodies of other comic characters like Koala Boy Wonder and literal interpretations of Catwoman, Two-face, and Penguin. There’s even a guest appearance by Christian Bale.
