The annual return of Sgt. Rigsby and His Amazing Silhouettes is cause for celebration. This is shadow puppetry for sinners, with wicked, witty stories about randy preachers, merry drunks, and a recurring character named Jenny, a singing chicken turned Parisian whore. In this year's show, innocent children search for their lost pets in a cruel metropolis—but the plot is just an excuse for Sgt. Rigsby (né Scot Augustson) to write testicle puns, an awkward sex scene between a hippo and a bear, and a conclusion wherein beer is the hero.
